Description
edit
Isturgia limbaria has a wingspan of 26–30 millimetres (1.0–1.2 in). Forewings can reach a length of 13–15 millimetres (0.51–0.59 in).[3] The male has feathered antennae, while those of the females are filiform. The upperside of the wings is yellow or orange yellow with a chocolate brown margin, less evident in the females. The underside of the hindwings is pale yellowish or greyish and strongly mottled, with visible longitudinal white stripes.
Biology
editThese day-flying moths fly from mid April to mid August [1] in one or two generation. The larvae feed on broom. They over-winter as a pupa.[4]
