About Kretania eurypilus
This description of Kretania eurypilus (originally referenced as L. eurypilus Frr., with synonym carmon Gerh.) comes from Seitz. The species is much smaller than previously documented related forms, and is very similar to Kretania argus. Unlike related species, the male of Kretania eurypilus is not blue on its upper side; instead, it is dark brown, matching the coloration of the female. Males often also bear red-yellow marginal spots in the anal area of the hindwing, just like females. This butterfly is found in Asia Minor, Mesopotamia, Turkestan, and North Persia, where it inhabits rocky slopes and is active from May to July. The larva is thought to feed on Astragalus echinus, because the butterfly is particularly abundant in locations where this plant grows.
