Drosophila quinaria
Drosophila quinaria is a species of fruit fly in the Drosophila quinaria species group, first described by Loew in 1866. Unlike most members of its species group, which feed primarily on mushrooms, D. quinaria has independently evolved a diet of decaying vegetative matter. The species is part of a speciose lineage of mushroom-breeding flies that have been studied for their specialist ecology, host-parasite interactions, population genetics, and evolution of immune systems.
