Davey, P., 2009: A widespread species in southern Britain, more local further north, the larva feeding on clover (Trifolium spp.), trefoil (Lotus spp.), medick (Medicago spp.) and related species. In Dorset, this day-flying moth ranges from locally common in unimproved dry grassland on chalky soils where common bird's-foot trefoil (Lotus corniculatus) occurs, to frequent in damp situations where greater bird's-foot trefoil (Lotus pendunculatus) grows. The following records refer to colonisation of sandy soils: Warmwell Heath, (Dr F Haines), Morden Heath, by day (Reverend F Carr), Studland, common by day (W Parkinson Curtis), Sandbanks, common both as larvae and as imagines (Reverend F Carr), Ashington, by day on 28 June 1992 (J Fradgley), Parkstone, by day on 14 May 1980 (Reverend S Pittis), West Moors, by day on 6 and 16 May, 2, 8 and 30 June 1994 (K Powrie), Cranborne Common, by day in 1975 (R Hatton), Merritown Heath, by day on 19 May 1999 (R Blake).

The name of the moth refers to Ursula Southeil a soothsayer and fortuneteller who was reputed to be hideously ugly and who lived during the reign of King Henry VIII. The face on the wing of the moth bears a striking resemblance to the surviving caricatures of her.
