Phyllonorycter heegeriella
(Zeller, 1846)
Wingspan c. 7mm.
Widely distributed throughout much of Britain, although local, this species is commoner in the south, occupying deciduous woodland.
One of several oak-feeding Phyllonorycter species showing a white forewing base colour, the narrow greyish basal streak is a useful identification aid.
The larvae form small blister mines on the underside of oak (Quercus) leaves, usually at a lobe, causing the tip to fold over. The mines are typically smaller than those of other oak-feeding species. They can be found in July and from September to October.
Adult moths fly in two generations, in May and again in August.
