Sub-angled Wave Scopula nigropunctata
Wingspan 29-34 mm.
The English name of this moth probably derives from the angled rear edge of the hindwings.
It is restricted within the British Isles to coastal undercliffs and woods in Kent and Sussex, but was formerly a little more widespread. It is also believed to be an occasional migrant.
The larval foodplants in the wild are not known, but in captivity it will accept dandelion (Taraxacum) and traveller's-joy (Clematis).
