This species is generally considered a migrant which can establish breeding colonies, sometimes short lived. A series of records at Blackcraig (VC 73) in 2021-2023 raises the possibility of local breeding.

Identification

Its larger size which is nearly twice the size of any British footmen, precludes any similar species. Only the female has the spots. Specimen or good quality photo required for record acceptance.

Recording Method

Attracted to light. Males greatly outnumber females for reasons unknown.

Life cycle

One generation July to September.

Larval foodplants

Dog lichen and other lichens and algae on oaks and other trees, and on rocks.

Habitat

Mature broadleaved woodland.
