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.
