Glacial Apollo

P. glacialis (Takashi et al. 2001) is much larger than Parnassius stubbendorfi of which it was once considered a subspecies. The blackish grey central spot of the cell is sometimes connected with the apical cell-spot by fuscous dusting along the sides of the cell, and the submarginal band of the forewing is more or less distinct and complete. The abdominal area of hindwing is deep black as far as the cell, clothed with white hairs; on and along the veins with blackish dusting. Collar, coxae and abdomen are laterally clothed with yellow or reddish yellow hairs. The wing underside is slightly yellow. In some Japanese specimens (from Hakodate) the cell-spots and the submarginal band of the forewing have entirely disappeared, or are only feebly indicated.

It is found in eastern China, Korea and Japan. The type locality is "in Hakodadi (North Japan)" (by lectotype designation).Hakodadi is located near the southern limit of Hokkaido.
