“…2A), located primarily around and along the hindwing vein Sc+R1, similar to the depiction in Figure 73 of Emsley's previous morphological analysis (Emsley, 1963). Similar scales have been described from light microscopy in other Heliconius species, but not previously in H. melpomene (Müller, 1912;Barth, 1952). The base of these special brush-like scales was more swollen and glandular as compared to other scales (Fig.…”

“…The observed sexual dimorphism in this trait suggests that these are androconia, and may be associated with a male sex pheromone (Emsley, 1963). Furthermore, earlier authors have identified brush-like scales in the hindwing androconial region that are the putative site for Manuscript to be reviewed pheromone production and emission (Müller, 1912;Barth, 1952). Here we investigate the structure of these scales using scanning electron microscopy.…”

Sex specific pheromones are known to play an important role in butterfly courtship, and may influence both individual reproductive success and reproductive isolation between species. Extensive ecological, behavioural and genetic studies of Heliconius butterflies have made a substantial contribution to our understanding of speciation. Male pheromones, although long suspected to play an important role, have received relatively little attention in this genus. Here, we combine morphological, chemical and behavioural analyses of male pheromones in the Neotropical butterfly Heliconius melpomene. First, we identify putative androconia that are specialized brush-like scales that lie within the shiny grey region of the male hindwing. We then describe putative male sex pheromone compounds, which are largely confined to the androconial region of the hindwing of mature males, but are absent in immature males and females. Finally, behavioural choice experiments reveal that females of H. melpomene, H. erato and H. timareta strongly discriminate against conspecific males which have their androconial region experimentally blocked. As well as demonstrating the importance of chemical signalling for female mate choice in Heliconius butterflies, the results describe structures involved in release of the pheromone and a list of potential male sex pheromone compounds.
