Ypsolopha horridella

(Treitschke, 1835)

---

Wingspan 16-21 mm.

Although this is perhaps the least attractive of the Ypsolopha species, the latin horridella is actually derived from horridus, meaning shaggy, and referring to the raised scale-tufts or crests on the dorsal part of the wings.

It is distributed locally in south and south-east England as well as north Wales and north-west England. The adults fly in July and August.

The larvae feed on the leaves of apple (Malus) or blackthorn (Prunus spinosa) in a slight web.
