Identification:
Deep orange color above makes it characteristic in the Nordic region. Females show pale spots in the black-bordered tips and margins of both upper wings; the male is solid black. Compared to hyale [Gul Høsommerfugl] the black rim covering the forewing tip above is running down along the outer margin in a very solid band, reaching the inner margin, running past the anal corner.
The underside of the forewing shows a deep yellow-orange center resembling the upperwing color, and much warmer than on similar hyale [Gul Høsommerfugl]. The hindwing is deep yellow with a greenish cast, and similar to hyale shows a black spot on the forewing and a white spot centrally on the hindwing. This seems like being double-red-encircled, giving it a more pronounced appearance than on hyale [variable].
Never shows the upperside at rest.
The wing tip of croceus is supposed to be narrower than on hyale [likely variable].
