Nut Leaf Blister Moth Phyllonorycter coryli

(Nicelli, 1851)

---

Wingspan 7-9 mm.

A common moth throughout much of the British Isles, this species is one of the few in the genus which mine the upperside of leaves, rather than the underside.

The larva forms a blotch on leaves of hazel (Corylus avellana), having a parchment-like upper surface, and causing the leaf to contort, especially if close to the margin. There can be several mines to one leaf, and the mines are very visible in late summer and autumn.

Being bivoltine, the adults are on the wing in May and again in August.
