The Damon blue (Polyommatus damon)

This small butterfly likes dry bushy places and open woods. As a caterpillar, it spends winter tended by ants. It becomes a butterfly in July and August in one generation. Sexual dimorphism characterizes the species. The back of the female is brown and that of the male blue with a wide grey border and protruding ribs. The other side of the wings is white with ochre rings and a white line across the hind wing, which also has black spots ringed with white.
