Acrocercops brongniardella

(Fabricius, 1798)

---

Wingspan 8-10mm.

This is a very local species, occuring mainly in southern England and southern Ireland
where it is found in open woodland. Occasional sporadic populations are to be found further north.

The larvae feed on Oak (Quercus spp.) and characteristically make twisting initial mines in the upper epidermis, which then join to form a large blotch, with a silvery appearance.

The moth is univoltine, being in flight at the end of July. It can also overwinter and be found again
in April and May.
