External Morphology Characteristics
The underside of the wings has a yellow color, with more orange in the basal, discal, and postdiscal zones of the forewing. On the upper side, the wings are a saturated orange color with a wide dark border along the marginal and submarginal zones. This butterfly is very similar to its sibling species, Colias caucasica. However, it is not possible to reliably differentiate between the two species based on the imago’s appearance. Despite their similarities, the two species have different distributions and habitats.
When lands, it keeps wings closed.
