Colias erate erate
A clouded yellow butterfly with a wingspan of 45-52 mm, resembles the clouded in shape and markings but of a lighter yellow colour, some females are white. The eastern lives in many different habitats, such as farmland, meadows, dry stony slopes, and mountain grassland. Host plants are mainly represented by legumes, such as crown-vetches (Coronilla spp.), birdsfoot-trefoil (Lotus corniculatus), alfalfa (Medicago sativa), red clover (Trifolium pratense), white clover (T. repens), and vetches (Vicia spp.). This migratory species flies March through October in several broods, and is highly mobile.
