Lulworth skipper  (Thymelicus acteon)

The Lulworth skipper is one of our smallest butterflies (3). Males are orange-brown with light spots and a black band on the forewings. Females are darker in colour than males and do not have this dark band. The underside of both sexes is orange-brown with no markings or spots (1). The caterpillar reaches 2.4 centimetres in length, has a green body with a darker green, yellow-bordered line along the back and pale yellow lines along the sides (2).
