Delia is a genus of flies in the family Anthomyiidae, commonly known as root maggot flies. Several species are significant agricultural pests, particularly of cruciferous crops and seedlings. The genus includes economically important species such as Delia platura (seedcorn maggot) and Delia radicum (cabbage maggot), whose larvae feed on seeds, roots, and developing plant tissues. Adults are small, drab flies that feed on nectar and are often mistaken for house flies.
