ABSTRACT
The relative abundance, density, distribution pattern and relation among pit diameter and larvae body size of Myrmeleon brasiliensis Návas were evaluated in two microhabitats: sheltered and exposed. The total of 282 pits were found in sheltered microhabitat and only 50 in the exposed. The density of M. brasiliensis was between one and 43 individuals per m(2). The distribution pattern of larvae tended from pooled to regular distribution as the density increased. In both microhabitats the larvae body size was positively correlated with pit diameter.

Avaliou-se a abundância relativa, a densidade, o padrão de distribuição e a relação entre o diâmetro do funil e o tamanho das larvas de formiga-leão Myrmeleon brasiliensis Návas em dois tipos de microhabitats: exposto e abrigado. Foram encontrados 282 funis no microhabitat abrigado e apenas 50 no exposto. A densidade de larvas variou de um até 43 indivíduos por m². O padrão de distribuição das larvas tendeu de uma distribuição agrupada para regular à medida que a densidade aumentou. Nos dois microhabitats o tamanho das larvas de M. brasiliensis foi positivamente correlacionado com o tamanho do funil.
