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 white, only in the female the short costal band placed outside the cell connected with the hindmarginal spot by an irregular dusty band, the glossy submarginal band of the forewing sharp but narrow, the male with small, the female with larger, crescent-shaped submarginal spots on the hindwing; on the latter the anal spot mostly centred with red.

Distribution

Alaska, British Columbia, Washington State, Nevada, California

Subspecies

• Parnassius clodius altaurus Dyar, 1903 Idaho and Wyoming has yellowish instead of red anal spots.
• Parnassius clodius shepardi Eisner, 1966 Shepard's Parnassian.Wawawai, Snake River Canyon, Washington
• Parnassius clodius baldur Edwards, 1877 distinguished by reduced and less sharp markings. In the male the hindmarginal spot is mostly absent on the forewing and the anal spot on the hindwing; the posterior ocellus is reduced as a rule; the female has no submarginal crescents on the hindwing, the anal spot is rarely centred with red; in both sexes the white dusting very thin, somewhat transparent.Occurs in the mountains to the East of the district of the principal form.Varies rather considerably, and forms on the one hand transitions to the coast form, on the other hand there occurs a further reduction of the pattern. Specimens with point-like, reduced posterior ocellus are not rare. These are ab. lusca Stichel. On the other hand, ab. lorquini Oherth., in which the ocelli are entirely absent, occurs sparingly. In the type of this form in addition all the black markings also are effaced except two narrow oblong spots in the middle and at the end of the cell of the forewing and some blackish dusting at the hindmargin of the hindwing. A further race from Montana, gallatinus Stich., is distinguished by the band-pattern of the male being in general weakly marked, while on the contrary there is a complete discal band outside the cell, as in the female of the typical form; hindwing without anal spot and with smallocelli; the female is more strongly marked, partly dusted over with black, the forewing with broader submarginalband, on the hindwing the submarginal lunulus and the anal spot strongly developed.
• Parnassius clodius claudianus Stichel, 1907 British Columbia, Vancouver Island.larger on the average, with much broadened marginal pattern on the forewing. Marginal and submarginal bands are merged into a broad stripe, through the middle of which runs only one row of small white crescents.In the female the black band-pattern is less intensive but broader, the connection of the costal spot and hindmarginal spot only shadowed as a narrow streak, on the hindwing very large marginal lunules, the anal spot without red dot. There are transitions to the typical form.
• Parnassius clodius incredibilis Bryk, 1932 Mount St. Elias, Alaska
• Parnassius clodius menetriesii H. Edwards, 1877 the two ocelli only remain as vestiges Wahsatch Mountains (Utah).
• Parnassius clodius pseudogallatinus Bryk, 1913 British Columbia Cascades of North Washington.
• Parnassius clodius sol Bryk & Eisner, 1932 California (Tulare to Modoc and S Siskiyou) usually at less than 7000'
• Parnassius clodius strohbeeni Sternitzky, 1945 California Santa Cruz Mountains apparently extinct
