## Summary

Aricia agestis, the brown argus, is a butterfly in the family Lycaenidae. It is found throughout the Palearctic realm, north to northern Jutland (Denmark), west as far as coastal Wales and east to Siberia and the Tian Shan.
It was described by Michael Denis and Ignaz Schiffermüller in 1775; the specific name agestis is thought to be a misspelling or typographic error for Latin agrestis, 'of the field.'
