Species of butterfly

The Scotch argus (Erebia aethiops) is a butterfly of the family Nymphalidae. In spite of its English name argus, it is not a close relation of the brown argus nor the northern brown argus.

Subspecies include: English colonies are found at Arnside Knott and Smardale Gill both in Cumbria. This species is found in most of northern Scotland, and in western areas in south Scotland. In Europe and Russia, these butterflies prefer the edge of pine forests and tall damp grassland in hills and mountains up to 2400 m. but there is a slightly marked sexual dimorphism. In Scotland, the subspecies caledonia has a narrower reddish yellow band and never contains more than three small eyespots. Three black spots are present on each hindwing. The egg is oval shaped, with 20 to 28 longitudinal ribs. The mature caterpillar is yellow brown, with a brown head. The pupae are yellow brown and relatively short and compact, reaching a length of
This species is rather similar to Erebia ligea, but the fringes on the edges of the upper side of the wings are more light grey, while in E. ligea they are white. Wheeler (1903) gives a short description of both species.

This species is univoltine. Adults fly from June to August. The eggs are laid singly on the leaves of grass. The larvae hatch after two weeks. The hibernating larva is reported to feed on Agrostis, Dactylis, Poa annua, Bromus erectus and other grasses. In Scotland the main host plants are purple moor grass (Molinia caerulea) and blue moor grass (Sesleria caerulea).
