}} Plebejus orbitulus, the alpine argus, is a butterfly of the family Lycaenidae. It is a high altitude species found in the Alps (ranging from the French Alps to Slovenia and Austria) and the mountains of Norway and Sweden. 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. The larvae feed on Astragalus alpinus. External links{{commons category|Plebejus orbitulus}}
