Ophiomyiinae
Ophiomyiinae is a of small within the , commonly known as . Members of this subfamily are characterized by their highly specialized association with monocotyledonous plants, particularly grasses and sedges. The group includes economically significant pests of cereal and pasture grasses. Larval development occurs within tissues, creating distinctive feeding damage.
