Acrocercops brongniardella
Brown Oak Slender
Wingspan 8 to10mm. The larvae of this species mine the leaves of Oak species. They characteristically make twisting initial mines in the upper epidermis, which then join to form a large blotch, with a silvery appearance.
Leafmines occur on Oak http://www.leafmines.co.uk/html/Lepidoptera/A.brongniardella.htm
In open woodland and other areas where the host species occur.
The moth is univoltine, being in flight at the end of July. It can also overwinter and be found again in April and May.
The larvae feed on Oak (Quercus spp.)
This is a very local species, occurring mainly in southern England and southern Ireland. Occasional sporadic populations are to be found further north. In the Butterfly Conservation's Microlepidoptera Report 2011 this species was classified as local.
It appears to be uncommon in Leicestershire and Rutland, where there are few records. L&R Moth Group status = D (rare or rarely recorded).
