Wingspan 20-31 mm. The smallest blue in the area. Flies on the dike in one long generation A butterfly flies in 2 generations when the year’s first newly emerged adults (1st generation) bring a new “brood” (“children”) capable of flight into the world in the same year. With 3 generations there are “grandchildren” as well in the same year. The number of generations determines in how many months of the year we can see the butterfly. from mid-June to August. Towards the end of the season mostly only worn males are seen. Keeps to the Heather but takes nectar from the many flowers on the dike. The male is territorial and keeps circling the same area. Overwinters as an egg on Heather. The species is declining in general, and the dike is its only habitat on Falster.
