The rose midge is a tiny yellow-brown or reddish fly that lays its eggs in newly developing bud and shoot tips. The hatching maggots feed on the growing tips. New buds and shoots are deformed and killed and the dead tissues turn brown or black. Abnormal flower development from damaged buds may also be seen.
