BEHAVIOUR: A fast flyer which when disturbed flies quite a distance before settling whereupon the forewings eyespot is briefly shown before being tucked away.  The butterfly always rests at a slight angle with their wings facing the sun in hot weather so as to maximise the capture of heat whereas on hotter days the wings are angled away from the sun so as to minimise the heat.  Due to the females secretive nature it is mostly males that are seen. HABITAT: Dunes, heaths, hillsides with bare dry patches.
