Eutreta diana is a species in the family Tephritidae, known as fruit flies in North America and picture wing flies in Europe.

[4] Females lay eggs in vegetative buds of several species and subspecies of sagebrush in western North America.

[5] Larvae induce woody galls near their oviposition site and feed on the plant internally until they mature.

Adults have "pale green eyes, white-dotted black wings, and bright red abdomens" (Goeden 1990).
