Scientific name: Lymantria dispar
July - August. Few sites in southern England. A large moth, the male is brown with feathery antennae. The female is larger than the male and creamy-white with darker, wavy lines. Found in woodlands, plantations, parks and gardens.
The female is superficially similar to the Black Arches but the latter species is smaller with the female Gypsy Moth having a thickset and blunt abdomen. The male resembles the darker form of the Black Arches but is again smaller than the Gypsy Moth with blacker colouration.
The male flies during the day but the female does not fly and apparently rarely travels far from the cocoon. The male also flies after dark.

- Countries – England
- This moth was presumed extinct in Britain in the early 1900s when breeding sites were cleared and drained. Occasional records, mainly from coastal southern England, since then are regarded as immigrants. However, it has become temporairily established in a very few areas, these all thought to be accidental introductions. The species is still frequent on Jersey, although confined to small areas, and it is an occasional immigrant on Guernsey.
Formerly frequent in the fens of East Anglia and occurs in a wide variety of habitats in mainland Europe.
