Effects of habitat loss on three insect assemblages in modified ecosystems of foothills of the Colombian Orinoquia / Efectos de la pérdida de hábitat en tres ensambles de insectos en ecosistemas modificados de Piedemonte en la Orinoquia colombiana

Abstract Introduction: The effects of habitat transformation have been widely studied and the effects are well-known at different levels of biological organization. However, few studies have focused on responses to this process at the level of multiple taxa in diverse taxonomic and functional groups. Objective: Determine the variations in taxonomic and functional diversity of ants, butterflies, and dung beetles, at a spatial and temporal level in a landscape mosaic of the ecoregion of the Colombian foothills. Methods: We assessed amount of natural habitat and landscape composition in four types of vegetation, during the highest and lowest rain periods. We collected butterflies with hand nets and used baited pitfall traps for dung beetles and ants. Results: Habitat loss positively affected ant and butterfly species richness, and negatively affected dung beetles. The abundance of ants and butterflies had a positive effect on the dominance of species in the transformed vegetation, for dung beetles the abundance was negatively affected by the absence of canopy cover. Habitat loss had no negative effect on functional diversity as there is no difference between natural and transformed vegetation. Conclusions: The amount of habitat, habitat connectivity and different types of vegetation cover were important factors in the maintenance of insect diversity in the modified ecosystems of foothills of the Colombian Orinoquia. The lack of a common spatial and temporal pattern shows that studies of multiple insect taxa should be carried out for biodiversity monitoring and conservation processes.

Resumen Introducción: Los efectos de la transformación del hábitat han sido ampliamente estudiados y son bien conocidos los efectos a diferentes niveles de organización biológica. Sin embargo, pocos estudios se han centrado en las respuestas a este proceso a nivel de múltiples taxones en diversos grupos taxonómicos y funcionales. Objetivo: Determinar las variaciones en la diversidad taxonómica y funcional de hormigas, mariposas y escarabajos coprófagos, a nivel espacial y temporal en un mosaico paisajístico de la ecorregión del piedemonte colombiano. Métodos: Evaluamos la cantidad de hábitat natural y la composición del paisaje en cuatro tipos de vegetación, durante los períodos de mayor y menor lluvia. Recolectamos mariposas con redes de mano y usamos trampas de caída con cebo para escarabajos coprófagos y hormigas. Resultados: La pérdida de hábitat afectó positivamente la riqueza de especies de hormigas y mariposas y afectó negativamente a los escarabajos peloteros. La abundancia de hormigas y mariposas tuvo un efecto positivo sobre la dominancia de especies en la vegetación transformada, para los escarabajos coprófagos la abundancia se vio afectada negativamente por la ausencia de cobertura de dosel. La pérdida de hábitat no tuvo un efecto negativo sobre la diversidad funcional ya que no hay diferencia entre la vegetación natural y la transformada. Conclusiones: La cantidad de hábitat, la conectividad del hábitat y los diferentes tipos de cobertura vegetal fueron factores importantes en el mantenimiento de la diversidad de insectos en los ecosistemas modificados del piedemonte de la Orinoquia colombiana. La falta de un patrón espacial y temporal común muestra que se deben realizar estudios de múltiples taxones de insectos para los procesos de monitoreo y conservación de la biodiversidad.

Distribution, diversity, endemism, and ecology of Nymphalid butterflies (Lepidoptera: Nymphalidae) in the Loxicha Region, Oaxaca, Mexico / Distribución, diversidad, endemismo y ecología de las mariposas Nymphalidae (Lepidoptera: Nymphalidae) en la Región Loxicha, Oaxaca, México

Abstract Introduction: The Loxicha Region of Oaxaca, Mexico, has been historically important for the study of Nymphalidae, second in the Papilionoidea for species richness. Describing the diversity patterns of this butterfly clade in Loxicha can improve our understanding of the evolutionary history of the Sierra Madre del Sur, the Mexican Pacific slope, and Mexico in general. Objective: To describe the temporal and spatial patterns of Nymphalidae diversity along an elevational gradient (80-2 600 m), and to compare Loxicha's fauna with other regions in Mexico. Methods: We obtained 28 756 records from 21 sites in the Loxicha Region, representing seven years of sampling. We estimate and analyze the diversity, endemism, and distributional patterns for three elevational levels and five vegetation types. We estimated species composition and similarity with other regions of the Pacific and Atlantic slopes. Results: We identified 189 taxa, including species and subspecies, from 85 genera and ten subfamilies of Nymphalidae. Loxicha contains 46 % of the species in the family recognized for Mexico, including ten endemic species and 56 endemic subspecies. Cloud forest and low elevations were the most diverse habitats for this family. There is a clear divergence between the Atlantic and Pacific faunas, and the Sierra Madre del Sur has two faunal components. High-elevation sites in Oaxaca, and in the neighboring state of Guerrero, have a distinctive fauna, apparently isolated from low-elevation sites, revealing an archipelagic distribution for cloud forest Nymphalidae. Conclusions: The Loxicha Region is one of the richest areas for Nymphalidae in Mexico. Distribution on the Pacific slope is determined by geographical history and ecological conditions, including elevation. Nymphalidae can be used to test hypotheses of biogeographic regionalization in Mexico.

Resumen Introducción: La Región Loxicha de Oaxaca, México, ha sido históricamente importante para el estudio de Nymphalidae, segunda en riqueza de especies en Papilionoidea. Describir los patrones de diversidad de este taxón de mariposas en Loxicha puede mejorar nuestra comprensión de la historia evolutiva de la Sierra Madre del Sur, la vertiente del Pacífico mexicano y México en general. Objetivo: Describir los patrones temporales y espaciales de la diversidad de Nymphalidae a lo largo de un gradiente altitudinal (80-2 600 m), y comparar la fauna de Loxicha con otras regiones de México. Métodos: Obtuvimos 28 756 registros de 21 sitios de la Región Loxicha, que representan siete años de muestreo. Estimamos y analizamos la diversidad, el endemismo y los patrones de distribución para tres niveles altitudinales y cinco tipos de vegetación. Estimamos la composición de especies y la similitud con otras regiones de las vertientes del Pacífico y Atlántico de México. Resultados: Identificamos 189 taxones, incluyendo especies y subespecies, de 85 géneros y diez subfamilias de Nymphalidae. Loxicha contiene 46 % de las especies de la familia reconocidas para México, incluidas diez especies endémicas y 56 subespecies endémicas. El bosque mesófilo y las elevaciones bajas fueron los hábitats más diversos para esta familia. Existe una clara divergencia entre las faunas del Atlántico y del Pacífico, y la Sierra Madre del Sur tiene dos componentes faunísticos. Los sitios de elevaciones altas en Oaxaca, y en el estado vecino de Guerrero, tienen una fauna distintiva, aparentemente aislada de los sitios de elevaciones bajas, lo que revela una distribución archipelágica para los Nymphalidae del bosque mesófilo. Conclusiones: La Región Loxicha es una de las zonas más diversas para Nymphalidae en México. La distribución en la vertiente del Pacífico está determinada por la historia geográfica y las condiciones ecológicas, incluida la elevación. Nymphalidae puede usarse para probar hipótesis de regionalización biogeográfica en México.

CARACTERIZACIÓN GENÉTICA DE LA POBLACIÓN DE Heliconius sara (Nymphalidae) EN LA ISLA GORGONA, COLOMBIA / Genetic characterization of the Heliconius sara (Nymphalidae) population in the Gorgona Island, Colombia

RESUMEN La estructura genética de poblaciones de mariposas con distribución en islas y sus pares continentales ha sido poco documentada para el neotrópico. Este estudio presenta la caracterización de una población de Heliconius sara con distribución en la Isla Gorgona, ubicada en la región del Pacífico Oriental Colombiano. Para esto se examinaron secuencias parciales de un marcador mitocondrial incluyendo información obtenida del GenBank. Se comparó la diversidad y estructura genética con sus conespecíficos continentales y también con congéneres, con los que comparte un ancestro común cercano en el clado Sapho-Sara. Para el análisis de diversidad y estructura genética se realizó un análisis de varianza molecular. Este análisis muestra que la distancia entre la población de la isla y sus pares en el continente es consistente con la variación intraespecífica observada en otras especies del género Heliconius. Para la reconstrucción de la genealogía y datación reciente en el Pleistoceno superior del grupo monofilético de secuencias de H. sara, se realizó un análisis de inferencia bayesiana, así como una de máxima verosimilitud. Del análisis demográfico se seleccionó un modelo histórico de flujo asimétrico desde la isla hacia el continente que sugiere baja resistencia de la discontinuidad geográfica a la dispersión de esta mariposa diurna desde la isla. Este es el primer estudio en examinar un posible evento de aislamiento de una población insular de mariposas en Colombia.

ABSTRACT The genetic structure of butterfly populations among islands and mainland has been poorly documented for the neotropics. This study shows a characterization of the Heliconius sara population with distribution on Gorgona Island in the Colombian Eastern Tropical Pacific region. We obtained partial sequences of a mitochondrial DNA, including information obtained from GenBank. The genetic diversity and structure were compared among the island population and their mainland conspecific, but also with congenerics, with those shared by a recent common ancestor within the Sapho/Sara clade. For the analysis of diversity and genetic structure, an analysis of molecular variance was performed. This analysis shows that the genetic distance between the island's population and that of the mainland is consistent with the intraspecific variation observed in other species of the Heliconious genus. For the reconstruction of the genealogy and the recent dating calibration in the upper Pleistocene of the monophyletic group of H. sara, a Bayesian inference was carried out as well as one of maximum likelihood. From the demographic analysis, an asymmetric gene flow model from the island to the mainland was selected. This model suggests low historical resistance of the geographic discontinuity to dispersal of this small and diurnal butterfly from the island. This is the first study to examine a possible event of local isolation of an island population of a butterfly in Colombia.

Distribution and diversity of Papilionidae and Pieridae (Lepidoptera: Papilionoidea) in Loxicha Region, Oaxaca, Mexico

Introduction: A reliable list of species and the analysis of diversity patterns of hyperdiverse taxa, like butterflies, are fundamental for monitoring and managing biological resources. Oaxaca is one of the most diverse states in Mexico for many groups including Lepidoptera and most of its diversity is unknown. Objective: To estimate and describe the species richness and diversity of Papilionidae and Pieridae along an altitudinal gradient and five vegetation types in the Loxicha Region, Oaxaca, Sierra Madre del Sur. Methods: Sampling effort comprised 222 collecting days during a period of seven years. We estimated the alpha diversity for 17 sites within an elevational gradient from 80 to 2 850 m, with five vegetation types: tropical deciduous forest (TDF), tropical sub-deciduous forest (TSDF), cloud forest (low and middle levels) (CF), oak-pine and cloud forest (high level) (OPCF) and oak-pine forest (OPF). Results: We obtained a list of 69 species (27 Papilionidae and 42 Pieridae), of 34 genera and five subfamilies, from literature records and fieldwork. These species are 60 % of the Pieridae and 48 % of the Papilionidae recorded for the state. The Loxicha Region has 36 % of the Pieridae and 30 % of the Papilionidae of Mexico. Both families present different species richness patterns by vegetation type. Papilionidae is richer in the TDF with 23 estimated species and most of the species of this family (84 %) occur below 500 m. Meanwhile, species richness of Pieridae has non-significant differences among vegetations types, except for OPF which has fewer species than the other types. The elevational gradient was divided into three levels (0-750, 750-1 800, 1 800-2 850 m) showing a reduction of species richness and diversity for both families at higher altitudes. Conclusions: Papilionidae species are more restricted to a vegetation type or elevational level than Pieridae species. Likely reasons are higher vagility (including migrations) and wider ecological tolerance of most Pieridae.

Introducción: Una lista de especies confiable y el análisis de los patrones de diversidad de taxones hiperdiversos, como las mariposas, son fundamentales para el monitoreo y manejo de recursos biológicos. Oaxaca es uno de los estados más diversos de México y mucha de su diversidad aun es desconocida. Objetivo: Estimar y describir la riqueza de especies y diversidad de Papilionidae y Pieridae en un gradiente altitudinal y cinco tipos de vegetación presentes en la Región Loxicha, Oaxaca, en la Sierra Madre del Sur. Métodos: El esfuerzo de muestreo comprendió 222 días a lo largo de siete años. Se estima la diversidad alfa para 17 sitios dentro de un gradiente altitudinal de 880 a 2 850 m con cinco tipos de vegetación: bosque tropical caducifolio, bosque tropical subcaducifolio, bosque mesófilo (nivel bajo y medio), bosque de pino-encino con bosque mesófilo (nivel alto) y bosque de pino-encino. Resultados: Se obtuvo una lista de 69 especies (27 Papilionidae y 42 Pieridae), de 34 géneros y cinco subfamilias, a partir de los registros en la literatura y el trabajo de campo. Estas especies representan el 60 % de los Pieridae y el 48 % de los Papilionidae registrados para el estado. A nivel nacional, la región Loxicha tiene el 36 % de las Pieridae y el 30 % de las Papilionidae del país. Las familias presentan patrones diferentes de riqueza de especies por tipo de vegetación. Papilionidae es más rica en el bosque tropical caducifolio con 23 especies estimadas y la mayoría de las especies de esta familia (84 %) están por debajo de los 500 m Mientras que la riqueza de especies de Pieridae no presenta diferencias significativas entre los tipos de vegetación, excepto por el bosque de pino-encino que tiene menos especies que los demás tipos. El gradiente altitudinal se dividió en tres pisos (0-750, 750-1 800, 1 800-2 850 m) con una reducción de la riqueza de especies y diversidad de ambas familias en altitudes mayores. Conclusiones: Las especies de Papilionidae están más restringidas a un tipo de vegetación o piso altitudinal que las especies de Pieridae. Probablemente por la gran vagilidad, valencia ecológica más amplia y capacidad de migraciones altitudinales de la mayoría de las Pieridae.

Temporal distribution of fruit-feeding butterflies (Lepidoptera, Nymphalidae) in the eastern extreme of the Amazon region

Rainfall is one of the most influential factors driving insect seasonality in the Amazon region. However, few studies have analyzed the temporal dynamics of fruit-feeding butterflies in the Brazilian Amazon, specially in its eastern portion. Here, we evaluated the diversity patterns and temporal distribution of fruit-feeding butterflies in a remnant of eastern Amazon forest in the Baixada Maranhense, northeastern Brazil. Specifically, we tested whether fruit-feeding butterflies are temporally structured and whether rainfall influences species richness and abundance. Butterflies were collected with baited traps in both the rainy and dry seasons for two consecutive years. In total, we captured 493 butterflies belonging to 28 species, 15 genera and eight tribes. Three species comprised about half of the overall abundance, and Satyrinae was the most representative subfamily. The fruit-feeding butterfly assemblage showed a strong temporal structure during the second year of sampling, but not during the first year. Species composition and richness did not differ between rainy and dry seasons, and neither abundance nor richness was influenced by rainfall. Our results indicate that seasonality is not a strong environmental filter in this region, and that other biotic and abiotic factors are probably driving the community structure. The predominance of palms in the Baixada Maranhense, which are used as host plants by larvae of several lepidopteran species (specially satyrines) and are available year-round, might have contributed to the observed patterns of temporal diversity.

Livre como uma borboleta: simbologia e cuidado paliativo / Free as a butterfly: symbology and palliative care

ResumoO objetivo do estudo foi investigar a relação entre as borboletas e os cuidados paliativos. A pesquisa foi esboçada no paradigma qualitativo, sendo adotada a etnografia, desenvolvida a partir da observação participante em dois Serviços de Cuidados Paliativos em Oncologia, no Brasil e em Portugal. Foi realizada uma revisão bibliográfica sobre o significado etimológico e simbólico das borboletas, seguida de encontros com especialistas que estudam esse inseto e sua presença na arte, livros e filmes. A simbologia da borboleta pode variar de lugar para lugar, de povo para povo, uma vez que sua semântica e representação estão associadas às diversas formas de vida, de culturas, de religiões e crenças. A presença constante e intrigante de borboletas nas paredes e vidraças dos hospitais estudados tem um significado nos cuidados paliativos, pois a metamorfose das borboletas é simbolicamente associada às transformações radicais que os seres humanos passam em suas vidas, sendo a morte percebida como uma possibilidade de renovação. Portanto, o rompimento do casulo representa a morte do corpo, com a alma ganhando vida em liberdade na imagem da borboleta. Assim, os cuidados paliativos, em sua filosofia teórica e prática aplicada, assistem e confortam esse processo de mudança na vida dos pacientes e familiares envolvidos, sem negar a morte e muito menos a dor e o sofrimento de uma doença em estágio avançado, vivenciada também por idosos.

AbstractThe aim of this study was to investigate the relationship between butterflies and palliative care. A qualitative ethnographic study was performed, based on participant observation in two Oncology Palliative Care Services in Brazil and in Portugal. A literature review on the etymological and symbolic meaning of butterflies, followed by discussions with experts who have studied this insect and its presence in art, books and movies, was undertaken. Butterfly symbols vary from place to place and from people to people, and the semantics and representation of the insect are associated with various forms of life, culture, religion and belief. The constant and intriguing presence of butterflies on the walls and windows of the hospitals studied has a significance for palliative care. The metamorphosis of butterflies is symbolically associated with radical changes in human lives, with death perceived as a possibility for renewal. Therefore, the breaking of the cocoon is the death of the body, when the soul achieves freedom in the image of the butterfly. Thus, palliative care, in its theoretical philosophy and applied practice, assists and eases this process of change in the lives of patients and their families, without denying the death, pain nor suffering experienced by the elderly during an advanced disease.

Species richness and relative species abundance of Nymphalidae (Lepidoptera) in three forests with different perturbations in the North-Central Caribbean of Costa Rica / Riqueza y abundancia relativa de especies de Nymphalidae (Lepidoptera) en tres bosques con diversos grados de alteración en el centro norte del Caribe de Costa Rica

Measurements of species richness and species abundance can have important implications for regulations and conservation. This study investigated species richness and abundance of butterflies in the family Nymphalidae at undisturbed, and disturbed habitats in Tirimbina Biological Reserve and Nogal Private Reserve, Sarapiquí, Costa Rica. Traps baited with rotten banana were placed in the canopy and the understory of three habitats: within mature forest, at a river/forest border, and at a banana plantation/forest border. In total, 71 species and 487 individuals were caught and identified during May and June 2011 and May 2013. Species richness and species abundance were found to increase significantly at perturbed habitats (p<0.0001, p<0.0001, respectively). The edge effect, in which species richness and abundance increase due to greater complementary resources from different habitats, could be one possible explanation for increased species richness and abundance. Rev. Biol. Trop. 62 (3): 919-928. Epub 2014 September 01.

La medición de la riqueza y abundancia de especies puede indicar la salud de un ecosistema y tener implicaciones importantes para la conservación y su regulación. Este estudio investigó la riqueza y abundancia de mariposas de la familia Nymphalidae en hábitats alterados y no alterados, primordialmente en la Reserva Biológica Tirimbina y en la Reserva Privada Nogal, Sarapiquí, Costa Rica. Se colocaron trampas cebadas con banano podrido en el dosel y sotobosque de tres hábitats: en un bosque primario, en el lindero entre un río y un bosque y en el lindero entre una plantación de bananos y un bosque. Se atrapó e identificó un total de 71 especies y 487 individuos durante mayo y junio 2011 y en mayo 2013. Se encontró que la riqueza y la abundancia de especies aumentaron significativamente en los hábitats de los linderos (p<0.0001, p<0.0001 respectivamente). El efecto de borde, según el cual la riqueza y la abundancia de especies aumentan a causa de la existencia de más recursos complementarios provenientes de dos hábitats distintos, podría ser una posible explicación del aumento en la riqueza y la abundancia de especies en hábitats alterados.

Lycaenid caterpillars (Lepidoptera, Lycaenidae) eating flowers of Dalea pennellii var. chilensis (Fabaceae) in the northern Chilean Andes

Lycaenid caterpillars (Lepidoptera, Lycaenidae) eating flowers of Dalea pennellii var. chilensis (Fabaceae) in the northern Chilean Andes. The shrub Dalea pennellii var. chilensis (Fabaceae) is reported for the first time as a host plant for three Neotropical Polyommatini (Lepidoptera, Lycaenidae, Polyommatinae): Hemiargus ramon (Dognin, 1887), Leptotes trigemmatus (Butler, 1881) and Nabokovia faga (Dognin, 1895), based on two collections performed in the western slopes of the northern Chilean Andes in two consecutive summers. The relative abundance was always above 90% for N. faga while it was always less than 5% for H. ramon and L. trigemmatus. Furthermore, N. faga was not found on inflorescences of other native Fabaceae examined in the study site. This pattern suggests a close relationship between N. faga and D. pennellii var. chilensis, at least at a local scale.

Butterflies of family Pieridae reported from Jammu region (Jammu and Kashmir) of India.

The present article incorporates detailed field observations of family Pieridae in Jammu region at different altitudes during spring, summer and autumn seasons of 2012-2013. The study revealed that 13 species of butterflies belonging to 10 genera of family Pieridae exist in the study area. Most members of Family Pieridae are white or yellow. Pieridae is a large family of butterflies with about 76 genera containing approximately 1,100 species mostly from tropical Africa and Asia.

Mariposas diurnas y nocturnas (Lepidoptera: Papilionoidae, Saturniidae, Sphingidae) del Parque Nacional Natural Gorgona, Pacífico Colombiano / Butterflies and moths (Lepidoptera: Papilionoidae, Saturniidae, Sphingidae) at the Natural National Park Gorgona, Colombian Pacific

Gorgona is a continental island at the Pacific coast of Colombia. For 26 years it was a prison but in 1986 it was declared a National Park, and the land was left aside for natural succession. This study presents a list of its Lepidoptera, compares it to a former study and discusses some ecological factors that could promote in situ biodiversity. Butterflies and moths were collected during three trips from October 2010 to May 2011. Butterfly observations were carried out along the main island paths. Baited traps using decomposed fruit, fish and chicken, were installed for three days at each zone (two kinds of bait per site) and sweep net catches were also made between 09:00h and 18:00h. For moths, black and white light traps were located in open areas. Town lights were also checked daily. Percent canopy cover was measured at each collection point. A total of 52 species belonging to seven families were found, of which 30 butterfly and 11 moth species are new records for the island. Cerro Trinidad and Sendero Chonta (22 and 20 species, respectively) were the richest places. Species richness did not decrease with canopy cover. Heliconious sara and Aeria eurimedia were the dominant species, but their distribution did not overlap. Three species were the most widely distributed in the island: H. sara (11 sites, 166 individuals), Calycopis cerata (10 sites, 71 individuals) and Ae. eurimedia (nine sites, 72 individuals). Catoblepia xanthicles occidentalis was found 87 years after the last report. Most species accumulation curves were not asymptotic suggesting that the diversity of the island is higher than expected. This study found twice as much the number of butterflies species reported for Gorgona and is the first record of moths for the island. Rev. Biol. Trop. 62 (Suppl. 1): 317-328. Epub 2014 February 01.

Gorgona es una isla ubicada en la costa Pacífica de Colombia. Durante 26 años fue una prisión, pero desde 1986 fue declarada Parque Nacional Natural, y desde entonces se encuentra en un proceso de sucesión natural. En este estudio se presenta una lista de los lepidópteros de isla Gorgona y se analizan algunos de los ecológicos que podrían promover la biodiversidad in situ de este grupo taxonómico. Se recolectaron mariposas y polillas durante tres viajes realizados entre octubre de 2010 y mayo de 2011. Las observaciones de las mariposas se realizaron a lo largo de los principales senderos de la isla. Se instalaron trampas cebadas con fruta, pescado y pollo descompuestos, durante tres días en cada zona de trabajo (dos tipos cebos por sitio) como también capturas con redes de entomológicas entre las 09:00h y 18:00h. En el muestreo de las polillas se utilizaron trampas de luz blanca y luz negra en zonas abiertas, la luz se reflejó sobre una pantalla blanca para maximizar la atracción. Además, se realizaron revisiones diarias en los alrededores de las luces artificiales del poblado. Se registró la cobertura del dosel del bosque en cada punto de muestreo. En total, se identificaron 52 especies pertenecientes a siete familias, de las cuales 31 de mariposa y 11 de polillas fueron nuevos registros para la isla. El Cerro Trinidad y el Sendero de la Chonta fueron los sitios de muestreo con mayor riqueza de especies (22 y 20, respectivamente). La riqueza de especies de mariposas no disminuyó con la reducción de la cobertura del dosel. Heliconious sara y Aeria eurimedia fueron las especies dominantes en número, pero su distribución no se superpuso. Tres especies fueron las más ampliamente distribuidas en la isla: H. sara (11 siitios, 166 individuos), Calycopis cerata (10 sitios y 71 individuos) y Ae . eurimedia (9 sitios y 72 individuos). Se reporta Catoblepia xanthicles occidentalis después de 87 años. La mayoría de las curvas de acumulación de especies no fueron asintóticas lo que sugiere que la diversidad de la isla es más alta de lo esperado. Este estudio contribuyó a incrementar en más del doble el listado de especies de mariposas reportadas para isla Gorgona y contiene los primeros registros de Polillas para esta localidad.

Butterfly Diversity and Status in Mandagadde of Shivamogga, Karnataka, India.

Biodiversity of butterflies in Mandagadde of Shivamogga of Karnataka carried out. Many butterfly species are strictly seasonal and prefer only a particular set of habitats and they are good indicators in terms of anthropogenic disturbances and habitat destruction. The richness and diversity of butterfly species is proportional to the food plant diversity, richness of flowers and intensity of rainfall. Unfortunately, butterflies are threatened by habitat destruction and fragmentation almost everywhere. A total of 52 species of butterflies belonging to 5 families were recorded during the study period. Among the 5 families, Nymphalidae dominated the list with 23 species, Paplionidae with 9 species, Pieridae and Lycaenidae with 8 species each and Hesperidae with 4 species. It is found that 9 species of butterflies are very common, 26 species are common and 17 species are rare in occurrence in Mandagadde.

Patrones de riqueza altitudinal de Papilionidae, Pieridae y Nymphalidae (Lepidoptera: Rhopalocera) en áreas montañosas de México / Altitudinal richness patterns of Papilionidae, Pieridae and Nymphalidae (Lepidoptera) in Mexican mountain areas

Butterflies constitute an useful group to investigate biodiversity patterns in specific geographic areas. The aim of this study was to describe the altitudinal patterns distribution and to recognize the main grouping factors of these families. We conducted a comparative study between the butterfly fauna (Papilionidae, Pieridae and Nymphalidae) of five Mexican mountain ranges (Sierra de Manantlán, Sierra de Atoyac de Álvarez, Loxicha Region, Teocelo-Xalapa and Sierra de Juárez), that included 34 sites of altitudinal ranges from 100 to 2 820m. Data was obtained from the Zoology Museum of the National University of Mexico, and comprised more than 60 000 butterfly records of 398 taxa (subspecies level) proceeding during the last 35 years. Fauna similarity between localities were analyzed using a cluster analysis by Sorensen similarity coefficient. Species richness showed a general tendency to decrease with altitude; the main difference was found between the locality with higher altitude and the rest of the sites. The principal factors affecting the identified clusters followed this order: the location in Pacific or Atlantic slope, and location on a particular mountain range. Three altitudinal levels (low elevations, up to 1 200m; intermediate elevations, from 1 200 to 1 800m; and high elevations, from 1 800 to 2 500m) were described in accordance to their main characteristic taxa. While Neartic elements were common in the highest altitudinal floor, Neotropical taxa were common in the lowest one. It was more difficult to characterize the intermediate level in which a high number of localities were clustered; this intermediate level was characterized by the presence of some endemic species. The results suggest that historical factors are preeminent in butterfly fauna composition in these areas. Future studies may include other Mexican mountain areas to obtain more information on the different factors (latitude, altitude, slope) influencing biodiversity patterns.

Las mariposas diurnas integran uno de los grupos más utilizados para el reconocimiento y monitoreo de la diversidad de una biota. Se realizó un estudio comparativo de las faunas de mariposas de las familias Papilionidae, Pieridae y Nymphalidae de cinco áreas montañosas de México, situadas en las vertientes Atlántico y Pacífico: las sierras de Atoyac de Álvarez, Manantlán, Juárez, y las áreas de Teocelo-Xalapa y la región Loxicha, con un total de 34 localidades representativas de los cinco transectos altitudinales, que comprenden de los 300 a los 3 100m de altitud. Se observó una tendencia general a la disminución de la riqueza con la altitud. Se analizó la similitud entre el total de localidades mediante el índice de Sørensen, diferenciándose en primer lugar las dos estaciones de elevaciones superiores (sobre los 2 500msnm), caracterizadas por pobres lepidóptero-faunas. En el grupo principal (32 sitios) las principales agrupaciones se dan de acuerdo, en primer lugar, a la pertenencia a la vertiente pacífica o atlántica, evento más histórico que ecológico y, después, las estaciones de una misma sierra o según tres diferentes pisos altitudinales, que se caracterizan de acuerdo con los táxones predominantes.

FILOGENIA DE ESPECIES DEL SUBGENERO Parides (LEPIDOPTERA: PAPILIONIDAE) BASADA EN SECUENCIAS DEL GEN CITOCROMO OXIDASA I / Species phylogeny of the Subgenus Parides (Lepidoptera: Papilionidae) Based in Sequences of Citochrome Oxidase I Gene

Parides Hübner es el taxón terminal de Troidini, un grupo de mariposas aposemáticas diversificado en el trópico y subtrópico, y modelos de varios complejos miméticos batesianos y mullerianos. Varias de las especies americanas de Parides son simpátricas e involucran poblaciones con variaciones intraespecíficas en los patrones de coloración, lo que genera confusiones en la definición del estatus taxonómico, especialmente en Colombia, punto de convergencia de las biotas de Norte y Suramérica. Este trabajo genera una aproximación a la filogenia de este grupo de mariposas y establece una definición más robusta de algunos de los taxones. Para ello se analizaron ejemplares pertenecientes a 15 taxones del subgénero americano Parides ( Parides ) como grupo interno y se utilizó como grupo externo especies de otros dos géneros estrechamente relacionados de Troidini. Para la extracción del ADN se utilizó el protocolo de Pascual et al. (1997) y DNeasy Kit. Se amplificó el fragmento final del gen Citocromo Oxidasa I (COI) de 476 pb. Para obtener una hipótesis filogenética se realizaron análisis de máxima parsimonia y se evaluó el soporte de cada nodo mediante Jackknife y soporte absoluto de Bremer. También se realizó un análisis bayesiano. La hipótesis resultante sugiere que el subgénero Parides es un grupo parafilético. Molecularmente se hicieron también válidas una especie y cinco subespecies. Los ejemplares analizados de Parides se dividieron en tres grupos principales coincidentes con los grupos Lysander (grupo 1) y Aeneas (grupos 2 y 3) de Rothschild y Jordan (1906).

Parides Hübner is a terminal taxon of Troidini, an aposematic butterfly group that is diverse in the tropics and subtropics, and a model of mullerian and batesian mimetic complexes. Several American species of Parides are sympatric and include populations with intraspecific variation in color pattern, thus creating confusion on their taxonomic status, mainly in Colombia where the biota of North and South America converge. This work presents a phylogenetic hypothesis of these butterflies and proposes a more robust definition of some taxa. For this, 15 taxa of the subgenus Parides were analyzed as ingroup; species of other two genera of Troidini, closer to Parides , were used as out-group. DNA was extracted using the Pascual et al. (1997) protocol and Quiagen DNAeasy kit. A terminal fragment of Cytochrome Oxidase I gen (476 bp) were amplified. We obtained a phylogenetic approximation using maximum parsimony and evaluated the branch support with Jackknife and absolute Bremer support. We also conducted a bayesian analysis. The resulting phylogenetic hypothesis suggested that Parides is a paraphyletic group; the molecular evidence support one species and five subspecies. The analyzed taxa were divided in three principal groups coincident with the Lysander (group 1) and Aeneas (groups 1 and 2) groups proposed by Rothschild and Jordan (1906).

Hesperioidea e Papilionoidea (Lepidoptera) coligidos em expedição aos Rios Nhamundá e Abacaxis, Amazonas, Brasil: novos subsídios para o conhecimento da biodiversidade da Amazônia Brasileira

Hesperioidea e Papilionoidea (Lepidoptera) coligidos em expedição aos Rios Nhamundá e Abacaxis, Amazonas, Brasil: novos subsídios para o conhecimento da biodiversidade da Amazônia Brasileira. Objetivando um aprimoramento do conhecimento da lepidopterofauna diurna da Amazônia brasileira, este estudo lista 180 taxa coligidos em cinco pontos distintos de dois afluentes do Rio Amazonas, envolvendo as áreas de endemismo Guiana e Rondônia. As coletas foram passivas e ativas e as diferentes localidades comparadas através de análise de Escalonamento Multidimensional Não-Métrico (NMDS).

Hesperioidea and Papilionoidea (Lepidoptera) collected in an expedition to the Nhamundá and Abacaxis rivers, Amazonas, Brazil: new insights for understanding the biodiversity of the Brazilian Amazon. Aiming at improving the knowledge of the diurnal lepidopterofauna of the Amazon rainforest, this study lists 180 taxa collected at five different points along two tributaries of the Amazon River, including the Guyana and Rondonia areas of endemism. The different localities were compared using Non-Metric Multidimensional Scaling analysis (NMDS).

Wolbachia endosymbiont infection in two Indian butterflies and female-biased sex ratio in the Red Pierrot, Talicada nyseus.

The maternally inherited obligate bacteria Wolbachia is known to infect various lepidopteran insects. However, so far only a few butterfly species harbouring this bacterium have been thoroughly studied. The current study aims to identify the infection status of these bacteria in some of the commonly found butterfly species in India. A total of nine butterfly species belonging to four different families were screened using PCR with Wolbachia-specific wsp and ftsZ primers. The presence of the Wolbachia super group ‘B’ in the butterflies Red Pierrot, Talicada nyseus (Guerin) (Lepidoptera: Lycaenidae) and Blue Mormon, Papilio polymnestor Cramer (Papilionidae), is documented for the first time in India. The study also gives an account on the lifetime fecundity and female-biased sex ratio in T. nyseus, suggesting a putative role for Wolbachia in the observed female-biased sex ratio distortion.

Riqueza de borboletas em dois parques urbanos de Curitiba, Paraná, Brasil / Butterflies's richness in two urban parks in Curitiba Parana, Brazil

In order to contribute to the knowledge of butterflies of Curitiba, were studied two urban municipal parks, the Botanical Garden which has total area of 178,000 m² and has a grove of preserved Araucaria forest only for scientific research, and the Municipal Park of Barreirinha which has total area of 275,380 m² and the area used for sampling of free access to population, with predominance of reforested vegetation. After 10 months of sampling, totaling 240 hours, 787 individuals and 166 species were registered, distributed to the families: Hesperiidae - 46 spp. (27.7 percent), Nymphalidae - 75 spp. (45.2 percent), Pieridae - 17 spp. (10.3 percent), Lycaenidae - 13 spp. (7.8 percent), Papilionidae - 8 spp. (4.8 percent) and Riodinidae - 7 spp. (4.2 percent), among which 22 species are new records for Curitiba, belonging to the families: Hesperiidae, Pieridae, Lycaenidae, Riodinidae and Nymphalidae. About the recorded species, only 33 percent are considered common to the parks, Sorensen similarity index of 48 percent confirm that each location has a characteristic lepidopterofauna and distinct from each other.

Com o objetivo de contribuir com o conhecimento das borboletas de Curitiba, foram estudados dois parques municipais urbanos, o Jardim Botânico que possui área total de 178.000 m² e um bosque de Floresta Ombrófila Mista preservada restrito a pesquisa científica, e o Parque Municipal da Barreirinha que possui uma área total de 275.380 m² e a área utilizada para as amostragens de livre acesso a população, com predominância de vegetação reflorestada. Após 10 meses de amostragem, perfazendo 240 horas, foram registrados 787 indivíduos e 166 espécies, distribuídos nas famílias: Hesperiidae - 46 spp. (27,7 por cento), Nymphalidae - 75 spp. (45,2 por cento), Pieridae - 17 spp. (10,3 por cento), Lycaenidae - 13 spp. (7,8 por cento), Papilionidae - 8 spp. (4,8 por cento) e Riodinidae - 7 spp. (4,2 por cento), dentre estas 22 espécies são novos registros para Curitiba, pertencentes as famílias: Hesperiidae, Pieridae, Lycaenidae, Riodinidae e Nymphalidae. Das espécies registradas, apenas 33 por cento são comuns a ambos os Parques, sendo que o índice de Similaridade de Sorensen de 48 por cento confirma que cada um dos locais estudados possui lepidopterofauna característica e distinta um do outro.

Lepidopterofauna (Papilionoidea e Hesperioidea) do Parque Estadual do Chandless e arredores, Acre, Brasil / Lepidopterofauna (Papilionoidea e Hesperioidea) of the Parque Estadual do Chandless and surroundings, Acre, Brazil

Tendo em vista a ausência de inventários lepidopterológicos no Estado do Acre e sua escassez no bioma amazônico brasileiro, o presente estudo objetivou contribuir para a construção da lista de Hesperioidea e Papilionoidea presentes no Parque Estadual do Chandless, localizado em uma região de difícil acesso e sem infra-estrutura para pesquisa científica. Durante 14 dias foram realizadas coletas com redes entomológicas, armadilhas e técnica de Ahrenholz em diferentes ambientes que caracterizam o parque e seus arredores. Foram identificadas ao total 482 espécies, nenhuma delas presente em listas vermelhas de espécies ameaçadas. É esperado um número significativamente maior de espécies após a adição de novas coletas em outras estações do ano, visto a estimativa Jacknife 1 não atingir sua assíntota, ou mesmo em comparação a inventários em áreas próximas que listam, após um intenso esforço amostral, até cerca de 1700 espécies.

Given the absence of Lepidoptera inventories in the State of Acre and its scarcity in the Brazilian Amazon forest, this study aimed to list the species of Hesperioidea and Papilionoidea present in the Parque Estadual do Chandless and surroundings. The access to the region is complicated and it has no infrastructure for scientific research. During 14 days, the butterflies were collected with entomological nets, traps and Ahrenholz's technique in different environments in the park and its surroundings. A total of 482 species were identified, none of them present in red lists of endangered species. It is expected a significantly greater number of species after the addition of new collections in other seasons, as the Jacknife 1 estimate does not reach its asymptote, or as compared to inventories in nearby areas that list nearly 1700 species after a greater sampling effort.

Las representaciones de los artrópodos en la arqueología colombiana / Arthropodod representations in colombian archaelogy

Diferentes tipos de artrópodos (miriápodos, crustáceos, insectos, arácnidos) y estadios del desarrollo de los insectos (pupas, larvas, adultos) fueron representados en diferentes materiales como cerámica, piedra y oro, a manera de expresión del conocimiento que los pueblos indígenas tenían y tienen sobre estos animales, y por la asociación que hicieron y hacen de sus características y conductas con la vida y la sociedad humana.

Different types of arthropods (i.e: myriapods, crustaceous, insects, arachnida) and insect development forms (pupas, larvae, adults) were displayed on various materials including ceramics, stone and gold as an expression of indigenous people ancient and present ideology on these animals and due to metaphors between their characteristics and behavior and life and human society.

Butterflies (Lepidoptera: Nymphalidae) Associated with Pig Carrions in Malaysia / Jurnal Sains Kesihatan Malaysia

An entomological study was conducted in Tanjung Sepat, Selangor, Malaysia in May until September 2007 revealing five species of butterflies (all from family Nymphalidae) were attracted to pig carcasses placed in an oil palm plantation. Euploea mulciber (Cramer 1777), Hypolimnas bolina (Linnaeus 1758), Elymnias hypermnestra (Linnaeus 1763), Mycalesis mineus (Linnaeus 1758) and Ypthima baldus (Fabricius 1775) came to the carcasses at different stages of decomposition. From this study, we know that nymphalid butterflies are attracted to carcasses but their roles are most probably unimportant in post-mortem estimation.
