Speciation by hybridization in Heliconius butterflies

Nature, 2006
Speciation is generally regarded to result from the splitting of a single lineage. An alternative is hybrid speciation, considered to be extremely rare, in which two distinct lineages contribute genes to a daughter species. Here we show that a hybrid trait in an animal species can directly cause reproductive isolation.

An Antiaphrodisiac in Heliconius melpomene Butterflies

Journal of Chemical Ecology, 2007
Gilbert (1976) suggested that male-contributed odors of mated females of Heliconius erato could enforce monogamy. We investigated the pheromone system of a relative, Heliconius melpomene, using chemical analysis, behavioral experiments, and feeding experiments with labeled biosynthetic pheromone precursors. The abdominal scent glands of males contained

Macrolides from the scent glands of the tropical butterflies Heliconius cydno and Heliconius pachinus

Organic & Biomolecular Chemistry, 2007
The four major components present in scent gland extracts of the male Costa Rica longwing butterflies Heliconius cydno and Heliconius pachinus were identified as 12- and 14-membered macrolides containing a C(18)-carbon skeleton. By use of micro-reactions and spectrometric examinations, structural proposals were made and subsequently proven by synthesis,

Patterns of pollen exploitation by Heliconius butterflies

Oecologia, 1981
We have studied pollen feeding habits of ten species of Heliconius butterflies in six major study areas in Trinidad and Costa Rica, and examined inter-species differences in pollen utilization under greenhouse conditions. We found: 1. Females collected significantly more pollen than males. 2.
