Description

Note: The wing pattern in ''Parnassius'' species is inconsistent and the very many subspecies and forms make identification problematic and uncertain. Structural characters derived from the genitalia, wing venation, sphragis and foretibial epiphysis are more, but not entirely reliable. The description given here is a guide only. For an identification key see Ackery P.R. (1975). Ground-colour yellow in male yellow or yellowish white in female. Resembles in pattern very closely the female of '' Parnassius felderi'': forewing grey at base and costal margin, and greyish glossy at distal margin; beyond the cell a curved discal band shaded with grey and a similar, sometimes less distinct, submarginal one. Abdominal area of hindwing dusted with black; a spot at anal angle, occasionally (especially often in female) prolonged to a short band; a more or less distinct undulate submarginal band; further, two red ocelli, the posterior one sometimes being all black on upperside or being wanting, remaining however distinct below; base of hindwing above spotted with red. Head and body yellow haired. Stichel in Seitz, 1906 (Parnassius). ''Die Groß-Schmetterlinge der Erde''. Die Groß-Schmetterlinge des palaearktischen Faunengebietes.
