RESUMO
The immature stages (egg, larva, and pupa) morphology, larval and oviposition behavior, and host plant of the "eighty-eight" butterfly Diaethria clymena janeira (C. Felder, 1862) are described. Eggs are laid singly under leaf, and have pronounced vertical ribs ending up in a crown. Larvae of early instars construct stick-like frass chains where they rest when not feeding. Late instars are green with reduced body scoli and long branched head scoli. Pupae are entirely green, and pupation occurs on the upper leaf surface. In general, morphology and behavior of immature stages are similar to those of related species in the tribe Callicorini.

RESUMO
Based upon light and scanning electron microscopy, the external morphology of the egg stage is described and illustrated for the following Heliconiini (Lepidoptera, Nymphalidae) from Rio Grande do Sul State, Brazil: Agraulis vanillae maculosa (Stichel, 1907), Dione juno juno (Cramer, 1779), Dione moneta moneta Hübner, 1825, Dryadula phaetusa (Linnaeus, 1758), Dryas iulia alcionea (Cramer, 1779), Philaethria wernickei (Röber, 1906), Eueides isabella dianasa (Hübner, 1806), Eueides aliphera aliphera (Godart, 1819), Heliconius ethilla narcaea Godart, 1819, Heliconius besckei Ménétriés, 1857, and Heliconius erato phyllis (Fabricius, 1775). A dichotomic key is provided for their identification, based upon differences at the levels of generic and ultrastructural morphology, and variation in host-plant use.
Utilizando-se da microscopia de luz e de varredura, são descritos e ilustrados os ovos dos seguintes Heliconiini (Lepidoptera, Nymphalidae) do Rio Grande do Sul (Brasil): Agraulis vanillae maculosa (Stichel, 1907), Dione juno juno (Cramer, 1779), Dione moneta moneta Hübner, 1825, Dryadula phaetusa (Linnaeus, 1758), Dryas iulia alcionea (Cramer, 1779), Philaethria wernickei (Röber, 1906), Eueides isabella dianasa (Hübner, 1806), Eueides aliphera aliphera (Godart, 1819), Heliconius ethilla narcaea Godart, 1819, Heliconius besckei Ménétriés, 1857 e Heliconius erato phyllis (Fabricius, 1775). Com base em diferenças morfológicas genéricas e ultraestruturais, associadas aos padrões de uso das plantas hospedeiras, elaborou-se uma chave dicotômica para a identificação das espécies.
