Agonopterix liturosa

(Haworth, 1811)


Wingspan 17-20 mm.

Reasonably common in England and Wales, becoming less so into Scotland. Also recorded in southern Ireland.

One of the more distinctive Agonopterix species, with its combination of well-marked purplish-brown forewings and buffish thorax and head.

The larva feeds on St. Johns-wort (Hypericum spp.), spinning together the shoots and feeding within.

The normal flight period for the adults is July to August, when the species is attracted to light.
