“…Furthermore, in Heliconius butterflies there has been a great deal of reporting of the outcome of evolutionary change and a great deal of theorizing about how it might occur, but very little documentation of it actually happening, as this publication attempts to do. Of particular interest is a possible relatively recent evolutionary change in Heliconius hermathena (Brown & Benson, 1977). However, unlike this paper, Brown & Benson did not document the actual change over time and did not suggest a possible relationship between a man-made effect on selective pressures associated with mimicry and the evolutionary change itself.…”

Four variable traits that determine mimetic colour patterns in the butterfly, Heliconius cydno, evolved between 1908 and 1984-91. There was a decline in the frequencies of alleles and phenotypes that confer resemblance to the co-mimic, Elzunia humboldt regalis, and an increase in the frequencies of alleles and phenotypes that confer resemblance to the alternative co-mimic, Heliconius erato chestertonii. Elzunia humbolt regalis was formerly common but is now restricted to forest fragments, whereas H. e. chestertonii occurs principally in disturbed habitats, where it is now common. Human disturbance of habitats is thought to have changed the relative abundances of the two co-mimics, and hence the selection operating on H. cydno. The form of H. cydno that is presumed to have been a near-perfect mimic of H. h. regalis is no longer found in the wild: this form would have been homozygous for the rarer alleles at all four loci. It has been possible to reconstruct this form on two occasions in the laboratory, breeding from partially heterozygous wild-caught female butterflies.

“…In contrast, late-instar caterpillars in the Heliconiini are brightly coloured, with diverse patterns occurring across species, particularly in those that exhibit pupal mating (Brown 1981;Mallet & Gilbert 1995). Such colorations probably function to advertise larval toxicity to predators, and, although few cases of mimetic convergence have been proposed, they could also provide species-specific information to searching males (Brown & Benson 1977). Signals that have evolved in a defence context are often also used in intraspecihc signalling (Summers et al 1999;Weller et al 1999;Jiggins et al 2001).…”

“…This case of ecological monophagy has been explained in part by Heliconius male searching and mating behaviours (Gilbert 1978(Gilbert ,1991. Males in the genus establish home ranges where they periodically visit habitat patches with adult resources and approach host plants looking for mates (Ehrlich & Gilbert 1973;Brown & Benson 1977;Mallet & Gilbert 1995). Moreover, in about half of the Heliconius species males specialize in searching for immatures.…”

“…As larvas são crípticas nos ínstares iniciais e apresentam coloração destacada no último instar (BROWN, 1981). As pupas possuem coloração variável, entre as espécies (BEEBE et al, 1960;TURNER, 1968) e/ou durante a ontogênese BROWN & BENSON, 1977;ANTUNES et al, 2002).…”

ABSTRACT. The egg stage of Heliconiini (Lepidoptera, Nymphalidae) from Rio Grande do Sul, Brazil. 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.
