Rhigognostis senilella
Rock-cress Diamond-back

(Zetterstedt, 1839)

Wingspan c. 21mm.

Distributed from northern England northwards through Scotland, where it is widespread and can be common in places, this species inhabits rocky places such as coastal or mountain habitats.

Adult moths are fairly distinctive, although can be variable in the intensity of their markings, and fly from August onwards, overwintering until spring.

The larvae feed on a number of plants such as rock-cress (Anachis) and dame's-violet (Hesperis), forming a slight web.
