Parnassius felderi, the Felder's Apollo, is a high-altitude butterfly which is found in Amur, Ussuri and China, North Korea and Japan.

P. felderi is considered conspecific with Parnassius eversmanni by most authors but a good (real/separate) species by Weiss (1999).

[1] 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 female more sharply and extendedly marked with grey; the forewing bearing beyond the cell a more or less complete median band, which is however sometimes indicated also in the male, and a submarginal band which is more sharply defined than in the male being, moreover, separated from the vitreous edge only by a row of white halfmoons.
