The Brown Argus is a small butterfly that is on the wing throughout the summer, between May and September. Adults feed on Common Rock-rose, which is also the caterpillars’ foodplant, together with various species like Crane’s-bills. The Brown Argus is found in dry, sunny and open habitats, including heathland and downland, and seems to be expanding its range as the climate warms up.
