Anthomyiidae (Anthomyiid Flies, Dung Flies)
The adults are generally greyish with black dots, resembling the Muscid flies. They occasionally feed at flowers with exposed nectaries, such as members of the Carrot family. The larvae have various habits, sometimes feeding on dung, scavenging in bird nests, and other rotting materials. The larvae of some species feed on bulbs, and can become pests of onions and lilies.
