Description[]

The wingspan is 25–30 mm. The male upperside varies from sky blue to a greyish or steely blue, and is unmarked apart from the narrow black borders and white fringes. The female is brown, often with a slight blue dust suffusion at the wing bases. The fore-wings end in a very pointed apex. Both sexes are clearly assigned by conspicuous white spots on the otherwise pale greyish brown or beige wing underside. The spots under the hind-wing are pure white and lack black centres. The butterfly flies from June to August depending on the location.

Ecology[]

The larvae feed on Astragalus alpinus.
