Mine: April - June

Pupa: Inside or outside the leaf

Notes: The mine is at he leaf margin and usually between two lobes (as shown). It has some similarities to that of Eriocrania subpurpurella, but is smaller when mature and is darker due to the frass adhering to the inner surface of the mine. The Eriocrania mine also has the typical 'spaghetti' frass.

The larva is illustrated and has dark plates on the pronotum and prosternum (which distinguishes it from that of Orchestes quercus).

Formerly Rhyncaenus pilosus.
