Brown Argus

Fascinating facts about the Brown Argus

• The brown argus occupies the whole Palearctic region, reaching its northern edge in northern Jutland, Denmark and stretching west to the coast of Wales. Its eastern range extends through Siberia to the Tian Shan mountains, and it is also recorded from the Canary Islands to the Pacific island of Askold. In mountainous areas it can be found up to about 10 000 ft, showing its ability to live from sea-level fields to high alpine zones.
• The specific epithet agestis was not a deliberate choice but probably a misspelling of the Latin word agrestis, which means "of the field". When Michael Denis and Ignaz Schiffermüller first described the butterfly in 1775 they used the form agestis, and later authors have noted the likely typographic error.
• Brown argus larvae are slug-like green caterpillars marked with a pale line along each side and are constantly tended by ants. They feed on plants such as common rock-rose, dove's-foot cranesbill and common stork's-bill, then spend the winter as fully grown larvae before pupating in the following spring.
• In recent years the brown argus has pushed northward in Britain, now reaching Yorkshire. The species is now widely distributed across south-east England and most of the Midlands, with colonies also recorded in Wales. This northern expansion follows a broader range increase that has been noted across the country. The butterfly remains common in its former southern stronghold while establishing new populations further north.
