About Isturgia limbaria (Fabricius, 1775)
Isturgia limbaria, first described by Fabricius in 1775, has a wingspan ranging from 26 to 30 millimetres, which is 1.0 to 1.2 inches. The length of its forewings measures 13 to 15 millimetres, or 0.51 to 0.59 inches. Males of this species have feathered antennae, while females have filiform, thread-like antennae. The upperside of the wings is yellow or orange yellow, marked with a chocolate brown margin that is less distinct in females. The underside of the hindwings is pale yellowish or greyish, heavily mottled, and has clearly visible longitudinal white stripes. This species occurs in parts of Central and Southern Europe, and it is considered extinct in Britain. These moths live in heathlands with heathers, along forest edges, and in scrubby areas.
