([Denis & Schiffermüller], 1775)
Wingspan c. 25mm.
The status of this species in Britain is uncertain. There is a single record from Cumbria in the late 19th century, backed up by a museum specimen, and being an alpine species in Europe, may remain undiscovered elsewhere in Britain.
It resembles U. uligonosalis, but has a much more distinct white reniform stigma on the forewing and noticeably paler hindwings with a dark border.
Abroad, the larva feeds on ragwort (Senecio).
