There are several British moths of the Arctiidae family. The footmen are usually put in a sub-family called the Lithosiinae. The genus Eilema has several species that are confusingly similar without experience. The buff footman (E. depressa) resembles the dingy footman but the wing shape is slightly more attenuated. It could also be mistaken for the orange footman which is more orange in colour but can fade. Like all the Eilema species, buff footman has a larva which feeds on lichen.
The length of the forewings is 15–17 mm. The moth flies from June to September depending on the location.The larvae feed on Lichen and Algae, especially on Pinophyta, but also on Oak.
