Nut Leaf Blister Moth - Phyllonorycter coryli

    Description

    Wingspan 7 to 9 mm. This is yet another very small, brown and white Phyllonorycter. The details of the patterning require very careful examination to determine the species and expert confirmation should be sought.

    ID guidance
    Habitat

    When to see it

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

    Life History

    The larva forms a blotch on leaves of Hazel having a silvery parchment-like upper surface, and eventually 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. This species is one of the few in the genus which mine the upperside of leaves, rather than the underside.
