Food Plant: Quercus spp. (Oak)

Egg: laid on the underside of a leaf

Mine: Jul, Sept-Nov

Notes: Makes a small mine (12mm long) usually on the leaf edge. The mine has many tiny, equally sized creases and the contraction of the mine causes the leaf to curl downwards - in some cases the lower and upper epidermis almost touch. If the mine is central in the leaf it does not contract very strongly. A very local miner with scattered records in England and Svotland. It was rediscovered in South Norfolk in 1982 and found to be local but common
