RESUMO
We report here the immature stages and natural host plants for three species in the so-called "Taygetis clade" of the nymphalid butterfly subtribe Euptychiina, Taygetis echo (Cramer, 1775), Taygetis sosis Hopffer, 1874, and Pseudodebis valentina (Cramer, 1779). The study was carried out at Finca Las Piedras in Madre de Dios department, Peru. Taygetis echo was observed utilizing a species of herbaceous bamboo, Olyra latifolia L. (Poaceae: Bambusoideae: Olyreae), T. sosis was found feeding on another species of herbaceous bamboo, Pariana lunata Nees (Poaceae: Bambusoideae: Olyreae), and P. valentina was found utilizing a species of woody bamboo, Guadua weberbaueri Pilg. (Poaceae: Bambusoideae: Bambuseae). We describe and provide photos of the immatures and host plants, as well as illustrations of the head capsules for each of these three species.

We describe here for the first time the complete immature life cycles and shelter structures of two Neotropical skipper butterflies in the subtribe Moncina, Troyus phyllides (Röber, 1925) and Thoon ponka Evans 1955, along with new natural host plant records for these species at Finca Las Piedras, Madre de Dios, Peru. Four eggs and a preantepenultimate larva of T. phyllides, as well as three eggs of Thoon ponka were collected in nature and each passed through five larval instars to adulthood. Troyus phyllides fed on a herbaceous species, Lasiacis ligulata Hitchcock & Chase (Poaceae: Panicoideae: Paniceae), while T. ponka fed on two congeneric herbaceous bamboo species, Pariana lunata Nees and Pariana sp. (Poaceae: Bambusoideae: Olyreae). We present photos of all immature stages and host plants, as well as illustrations of the shelter structures and the head capsules for each of these two species.
