Pest. - Leafroll midges, Dasineura spp.; larvae are small, white maggots 2 to 3 mm long; occur in the Eastern United States; produce one to two generations per year.
Injury. - Several tiny maggots feed together in young, unfolded leaves of ashes in early spring, etching the tender epidermis and keeping the leaves from unfolding; damaged leaves roll, curl, distort, and may fall off.
Prevention and Control. - Natural control is usually adequate; trees should be kept in vigorous condition; direct controls are rarely needed.
