456 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.
