Brown Argus (Aricia agestis)
The Brown Argus is moderately common in grasslands where Rockrose or Cranesbills grow, mainly in the Mendips and Poldens.
Both sexes are brown above with a band of orange cells following the outer edge of the wings. This makes them tricky to distinguish from some female Common Blues which can also be brown above. The detail of the underwing markings must be seen to ensure correct identification
Images L-R: male;: female; underside - note that there is no spot on the forewing nearer than halfway to the body.
Flight Period: May-September
