Chrysanthemum midge
Quick Summary
The chrysanthemum midge, also known as Diarthronomyia chrysanthemi, is a small, orange fly belonging to the gall midge family. These insects are characterized by their delicate appearance, beaded antennae, and wings with few veins.12
The larvae of the chrysanthemum midge typically inhabit the leaves and flowers of chrysanthemums, particularly in greenhouse environments. Their presence often leads to the formation of galls, which are abnormal tissue swellings on the plant. While the chrysanthemum midge is a pest, some species of gall midges are beneficial, preying on aphids, mites, and scale insects.12
