Presentation of all the 54 species composing the genus Parnassius with all their prospecies, in an attempt to clarify their classification, by presenting a check-list and a phylogenic tree, as well as comments on the validity of certain taxa.

Illustration in colours (scale 1/1) of both males and females of each species and prospecies (with some typical subspecies). Large scale and regional distribution maps of all the species within the holarctic region (Eurasia and North America for widely distributed species), Europe and the Himalayan region, for more localized species. Maps of France for the 3 species present, with indication of the subspecies.

Heading for each species, with details allowing their identification, references to the food plants, and information about the altitude and the flight periods.

Although written in French, this booklet is designed to be completely accessible for non French-speaking readers (Phylogenic tree and systematic check-list using Latin nomenclature throughout, maps, colour plates, flight periods and altitudes and food plants (Latin names).

At midway between specialised monographs and regional field guides, this compact but up-to-date and documented booklet gives the non Parnassius-specialised entomologist essential information on the knowledge and the repartition of all the Parnassians of the world.
