Common Blue Butterfly

The Common Blue butterfly, Polyommatus icarus, is, as the name suggests, pretty common. Males usually have wings that are blue above with a black-brown border and a white fringe. The females are generally brown above with a bit of blue and some orange spots. Colourings, however, do vary quite considerably depending upon location. Wingspan is between 1 and 1.4 inches (28 to 36mm).
