Parornix betulae (Stainton, 1854)

Wingspan: 9-10mm

A bivoltine species with adults on the wing in May and August. It is an occasional visitor to light but can also be taken from branches of the foodplant by beating. Recorded from Las Descargues and many of the woodland traps. Mines are common.

Larval feeding takes place in the leaves of Carpinus betulus, and Fagus sylvatica initially in a gallery which is developed by the second instar larva into a between vein blotch mine with pupation taking place in a cocoon often spun under the edge of an upward folded leaf.
