Characteristics of the adults
The upper side of Colias werdandi is very pale white-yellow, the outer edge is gray-black and narrow. In front of him runs a submarginal row of worn, coherent gray-black spots. The black center point of the forewings is large, the fringes on the edge of the wing are pale red. The underside of the forewings is dirty white, the center point is cored white. A row of blackish, wedge-shaped spots runs in front of the outer edge. The underside of the hind wings is green-gray, the whitish or yellowish central point is bordered in red. The wide outer edge is much lighter than the forewing and the entire hem is rose-red. The female has light submarginal spots and darkened hind wings.

The moths fly in one generation in June.
Systematics
The species was described in 1839 by Johan Wilhelm Zetterstedt using a butterfly from Tornio (Swedish Torneå), Lapland ( Finland ), as Colias nastes werdandi in Insecta Lapponica . The species has long been considered a subspecies of the Colias nastes Boisduval, which occurs in polar North America and Northeast Asia , 1832. Russian entomologists in particular assigned them to Colias tyche (Boeber, 1812). Recent studies have shown that the species is morphologically very different from the other two. The classification of Colias nastes zemblida Grieshuber, 1998, which occurs on Novoja Semlja, is controversial, it could also be a subspecies of Colias werdandi .
etymology
