Explanation of Names
The names marshallii
, and triangularis
have been treated variously as subspecies or synonyms of M. oregonensis
, or as distinct species. Most references seem to treat them under M. oregonensis
; however, in the Orthoptera Species File
, two are currently treated as distinct species.
Dark, often blackish, with pattern usually little contrasting, wings about as long as or shorter than pronotum, widely separated over the back, and roughly oval in shape. Hind tibiae brownish blue to blue. Males with cerci rounded oblong and roughly two to three times as long as wide; with furculae well-developed, narrowly triangular and often slightly divergent, reaching nearly to middle of supra-anal plate.
mostly in the Rocky Mountains in Montane to Alpine environments from southern British Columbia and Alberta southward into Utah and northern New Mexico.
Relatively dry, often gravelly and gently sloping grassy areas, often openings in conifer forest or woodland.
