Rhagoletis indifferens

Description

The western cherry fruit fly (Rhagoletis indifferens) is a pest that lives only on cherries. The adult form of this insect is slightly smaller than a housefly, with white stripes across the abdomen, yellow markings near the base of the wings, and black markings on the wings. The larva, which is the stage of this insect's lifecycle that causes the actual damage to the fruit, is similar to a typical fly larva or maggot. Female flies lay eggs in the cherries, where the larvae feed for 1–2 weeks before exiting. Western cherry fruit flies damage fruit by feeding, in both the adult and larval stages.
