Heliconius Butterfly Pictures
Speciation
Heliconius butterflies are also models for the study of speciation. Two closely related species, H. cydno and H. melpomene, hybridized to create to the species H. heurippa. Assortive mating reproductively isolates H. heurippa from its parental species. This is a rare example of speciation through hybridization.
