This species is not local to the Yeldham area. It is found in woods in the East Midlands. Our nearest sites are near Huntingdon in Cambridgeshire. On a good day a number could be seen hovering over low blackthorn shrubs in Monks Wood, near Woodwalton. On June 3rd 2011, they were active in the warm sunshine, making brief landings to rest or to take nectar. The pale green flowers of the Bryony vines were favoured.

There is only one brood per year with the adults in flight for a short period in late May to early June. The Butterfly over-winters as an egg. Food plants are wild Prunus, usually Blackthorn.
