Abstract

The morphologies of the penultimate and last instar larvae and pupae of the hairstreak butterfly Porthecla ravus (Druce 1907) are described and illustrated for the first time. Larvae feed on flower buds and/or leaf primordia of Xylopia aromatica (Lam.) Mart. (Annonaceae). As observed for the closely related genus Oenomaus Hübner 1819, host plant records for P. ravus suggest a feeding specialization on Annonaceae. The obtained results on immature stage morphology and host plant use are compared with other related genera in Eumaeini and discussed.
