Platyperigea was demoted to a subgenus of
Caradrina by Hermann Hacker in 2004 (see Print References below)
Explanation of Names
MONTANA: from the Latin "montanus" (belonging to a mountain); perhaps a reference to the terrain where the type specimen was collected (?) - presumably in Europe, where the species is widespread
Identification

hindwing white with dark-spotted terminal line
Range
western North America: Alaska, Yukon, Northwest Territories, south to California, west to New Mexico, north to Manitoba, plus several recent records from southern Ontario (species may be listed under one of its synonyms; see Synonyms section above)
also occurs throughout Europe and western Asia
Food
larvae feed on leaves of alfalfa (Medicago sativa), dock (Rumex spp.), hawkweed (Hieracium spp.), plantain (Plantago spp.), sow-thistle (Sonchus spp.)
Remarks
The species was described by Bremer in 1861.

Rare Sand Quaker (
Caradrina meralis) forewing has very faint or absent lines
Caradrina multifera has bolder markings, brownish spots in the subterminal area, and doesn't occur west of Manitoba/Minnesota (except for disjunct population in British Columbia)
