426 butterfly species were sampled on six field-trips to Morro do Diabo and are listed with their dates of capture and where they are recorded. A variety of collecting methods was used, including standard insect nets and traps. Adult butterflies were attracted to many substances, including, wet sand, bird droppings, excrement and decaying fruits and animais. The results were compared with anothers richest butterfly communities. The following taxonomic changes are included: Pyrrhopyge aziza subnubilus Hayward, 1935 nom. rev., stat. nov., comb. rcv.; Telemiades meris meris (Plötz, 1886) sp. rev.; Quadrus u-lucida mimus (Mabille & Boullet, 1917) nom. rev., stat. nov., Peba verames (Schaus, 1902) sp. rev., comb.n.; Peba striata Mielke, 1968, syn. nov. of Peba verames. Zonia zonia diabo ssp.n. is described.
