Food Plant: Quercus (Oak); occasionally Castanea sativa (Sweet Chestnut)            

Mine: May - June

Notes: Blotch mine, frass in long threads. Larva white, head pale brown. The mine can be confused with that of Orchestes pilosus, but the mine of O.pilosus is darker and smaller when mature. The frass of D.subpurpurella is also typically 'spaghetti' like in appearance. Formerly Eriocrania subpurpurella. Mine shown, with dead larva, on Castanea sativa
