Description

Wing span: 30 - 36mm
 
This attractively-marked Skipper is quite rare, but has been spreading to new sites in recent years. The silvery blotches on the underwings are diagnostic.
 
It is restricted to southern England, being mainly found in Dorset, Hampshire, Wiltshire, Surrey and the southern Chilterns.
 
It is confined to chalk grassland where the turf is short and there are patches of bare ground.
 
Adults are usually on the wing from the end of July to the beginning of September. The species over-winters as an ovum.
 
The sole larval foodplant is Sheep's-fescue (Festuca ovina). Adults often feed on purple flowers such as Dwarf Thistle and Scabious.
 
Males perch in a sunny position to await a female. Aerial courtship is followed by mating on the ground. Individuals are only active when the temperature exceeds 20°C.
 
This species is listed as Near Threatened in the latest Red List of British Butterflies (PDF).
