Barred Tooth-striped Trichopteryx polycommata

Wingspan 33-36 mm.

Locally distributed in scattered localities throughout England and Scotland, occupying woodland, chalk downland and scrubby areas.

A spring flyer, on the wing in March and April, the larvae feed in late spring and summer on wild privet (Ligustrum vulgare) and ash (Fraxinus).

There is a scarce melanic form, ab. caliginosa, which has occurred in Sussex, and some northern forms have a more contrasting pattern than typical specimens.
