These butterflies inhabit grassy flowery places at an elevation of 200–1,500 metres (660–4,920 ft) above sea level. [3]
Plebejus argyrognomon has a wingspan of 28–34 mm. These small butterflies present a sexual dimorphism. The upperside of the wings is violet-blue in males, with a narrow, black border and a white fringe, while in the females it is dark brown, with black bordered orange lunules at the outer edge, especially visible on the hindwings. [4] The underside of the wings is light beige in both sexes, with several black spots surrounded by white, an orange stripe and a marginal series of black spots pupillated in silvery blue-green. Caterpillars are pale green with orange brown longitudinal stripes, up to 20 millimeters long.
This species is similar to Plebejus argus , Plebejus idas , Plebejus pylaon and Polyommatus escheri . [5] In Plebejus argyrognomon the underside of the wings is similar to Plebejus argus and Plebejus idas , but the background color is more gray and the black spots are relatively smaller.
The species fly in two broods [5] from May to August depending on the location. The larvae feed on Coronilla varia , Securigera varia , Trifolium repens , Melilotus officinalis , Medicago sativa , Lotus corniculatus , Onobrychis viciifolia , Vicia sativa and Astragalus glycyphyllos . [1] Larvae are attended by ants Lasius niger , Lasius alienus , Myrmica sabuleti , Myrmica scabrinodis and Camponotus vagus . [6] [7]
