title: Sympatric speciation based on allelic changes at three Loci: evidence from natural populations in two habitats.
abstract: Allelic changes at three loci largely explain Chrysopa downesi's sympatric speciation from a Chrysopa carnea-like ancestor. Disruptive selection first produced a stable polymorphism based on a single pair of alleles that adapted individuals to two habitats, and second, it established seasonal asynchrony in reproduction through allelic substitutions at two loci.
