1880 Barred Tooth-striped Trichopteryx polycommata
([Denis & Schiffermüller], 1775)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.
