692 Agonopterix subpropinquella
(Stainton, 1849)Wingspan 16-22 mm.
A fairly common species throughout much of England and Wales, becoming scarcer into Scotland and Ireland.
It can be confused with other species such as A. propinquella, and is usually best identified by dissection. The form rhodochrella is more distinctive, with darker head and thorax, and more prominent wing markings.
The larvae feed on knapweed (Centaurea spp.) or thistle (Cirsium), and the adults emerge from August, hibernating over the winter. They can sometimes be encountered until the following May.
