About Colias aurorina Herrich-Schäffer, 1850
Colias aurorina Herrich-Schäffer, 1850 is one of the largest species in the genus Colias, with a wingspan ranging from 35 to 70 mm. On males, the upper wing surface is a dusky orange-yellow, marked with a moderately broad blackish-brown marginal band. Yellow veins cross this band at the wing apex. The forewing has a rather large, blackish-brown spot at its middle. The hindwing’s middle spot is large and orange-red. Females have a ground color that is a somewhat brighter red. Their dark marginal band holds large yellow spots. On the female hindwing, these yellow spots form a band with a dark edge on its proximal side, and the dark marginal band itself is not fully developed (obsolescent).
