Local in gardens, meadows and rough grassland in southern England and southern Wales. In Hampshire apparently extending its range in recent years, now widespread and generally common, and recorded for the first time on the Isle of Wight at Shanklin in 1996. Wingspan 13-15 mm. The moth flies over the foodplant in late afternoon and evening. Differs from
D. flavidorsana by the comparatively broad medio-dorsal blotch of the forewing and the fuscous hindwing which is light basally; in the male the costal fold of the forewing is longer and extends to the median fascia [Bradley]. Larva feeds within roots of Ox-eye Daisy.
