Barred Rivulet Perizoma bifaciata
(Haworth, 1809)
Wingspan 20-26 mm.
Widely distributed over England and Wales, though usually local, it is scarce in southern Scotland and Ireland.
It flies in July and August, and is attracted to light.
The larvae feed mainly on the seeds of red bartsia (Odontites verna). It spends the winter as a pupa, and unusually for the family, may overwinter more than once in this stage before emerging.
