is 6-8 mm. There are two generations per year with adults on wing in May and again in August
The larva
e feed on Ulmus glabra, Ulmus laevis, Ulmus minor and Ulmus pumila. They mine
the leaves of their host plant. They create a short, roundish to oval, somewhat inflated, lower surface tentiform mine, often crossing a lateral vein. The epidermis has several lengthwise folds. Pupation takes place in a tough, greenish cocoon which lies freely in the mine.
