Irish Distribution: Possibly extinct! Previously recorded from Benaughlin Hill near Florencecourt, Fermanagh around 1914 and Divis Mountain, Antrim in 1900. Recent searches in Fermanagh have failed to locate the moth. However it may still exist as the habitats are remote and the flight period is late making detection difficult. Elsewhere in Ireland it is known from Donegal, Sligo, Mayo and Galway.

Ecology: A rare moth inhabiting damp rushy , upland pasture and open moorland. It seldom comes to light although females apparently fly in late afternoon. The foodplant is believed to be Creeping Buttercup Ranunculus repens. It overwinters as an egg.
