Brown Argus: the brown blue

Brown Argus: the brown blue

The brown argus (Aricia agestis) is far from common and was, for many years, thought to be in decline because of its dependence on chalk and limestone grassland. However, more recently, it seems to have adapted to other habitats and so now appears to be seen a little more and in more varied places.

Despite being brown it is a member of the blues! The females of many blue butterflies are brown but the brown argus is quite a small butterfly; both sexes have a deep brown colouring to the wings and has very clearly defined orange dots that go along the complete edges of the wings. Not easy to identify in flight, you need to see it at rest or feeding to be sure.

The species has two broods a year which seem to overlap and so you can find brown argus from May right through until mid-September.
