(B71) BF1916

Clouded August Thorn Ennomos quercaria

(Hübner, [1813])

Wingspan c. 28-35mm.

Only doubtfully recorded in Britain on two occasions, once in the 19th century, then again in south-east England in 1992, this species occurs in mainland Europe, generally in the south, but is rather local.

The adults fly in June and July and are similar to September Thorn, but somewhat paler. The larvae feed on oak (Quercus spp.).
