onius butterflies are models for the study of speciation. Hybrid speciation has been hypothesized to occur in this genus and may contribute to the diverse mimicry found in Heliconius butterflies. It has been proposed that two closely related species, H. cydno and H. melpomene, hybridized to create the species H. heurippa. In addition, the clade containing Heliconius erato radiated before Heliconius melpomene, establishing the wing pattern diversity found in both species of butterfly. In a DNA sequencing comparison involving species H. m. aglope, H. timareta, and H. m. amaryllis, it was found that gene sequences around mimicry loci were more recently diverged in comparison with the rest of the genome, providing evidence for speciation by hybridization over speciation by ancestral polymorphism.

Hybridization is correlated with introgression. Results from Supple and her team have shown SNP's being polymorphic mostly around hybrid zones of a genome, and they claimed this supported the mechanism of introgression over ancestral variation for genetic material exchange for certain species. Selection factors can drive introgression to revolve around genes correlated with wing pattern and color. Research has shown introgression centering on two known chromosomes that contain mimicry alleles.

Assortive mating reproductively isolates H. heurippa from its parental species. Melo did a study on the hybrid H. heurippa to determine its mating habits regarding preference between other hybrids and its parental species. The results showed H. heurippa chose to reproduce via backcrossing, while the parental species were highly unlikely to reproduce with the backcrosses. This is significant, because hybrids' mating behavior would relatively quickly isolate itself from its parental species, and eventually form a species itself, as defined by lack of gene flow. His team also hypothesized that along with a mixed inheritance of color and pattern, the hybrids also obtained a mixed preference for mates from their parental species genes. The H. heurippa likely had a genetic attraction for other hybrids, leading to its reproductive isolation and speciation.

Although rare, Heliconius butterflies are an example of homoploid hybrid speciation, i.e. hybridization without changing the number of chromosomes. Aposematism, using warning colors, has been noted to improve species diversification, which may also contribute to the wide range of Heliconius butterf
