|scientific name Grylloblatta scudderi Kamp|
Likely as G. c. campodeiformis: cold damp locations near mountain tree lines and glacial bogs.
Males of this species can be recognized by the fact that they are larger than any other Canadian Grylloblatta, although females are about average size for this genus. Antennae have either 36 or 37 segments, and legs and body are densely covered in a fine tan coloured pubescence, with major body setae conspicuous in males only (Kamp 1979). Compared to other Grylloblatta, the legs are particularly long, and metatibia ratios can be used in particular to distinguish between other species of this genus.
Individuals probably take several years to develop and reproduce, as G. campodeiformis. Type specimens were collected below a glacier on a snowfield at 1951m above sea level. Specimens collected were restricted to this site only.
Rare and isolated populations, but probably not immediately threatened.
Likely similar to G. c. campodeiformis: Adults and juveniles are omnivorous. The main component of the adult diet is wingless crane fly (Chionea obtusa) adults, as well as collembola, microcoryphia, oribatid mites, adult diptera, aphids, and staphylinids. Juveniles also mainly consume other arthropods. These insects have also been observed eating moss and decaying vegetation.
Known only from British Columbia type locality, Whistler Mountain, Garibaldi Provincial Park, B. C.
Holotype (male) and Allotype (female) collected on Whistler Mountain, in Garibaldi Provincial Park, British Columbia July 13, 1970.
