One of the most widely distributed Nearctic grasshoppers, occurring throughout Canada and the United States including Alaska, the Northwest Territories and Yukon, and found in a variety of habitats, including bogs, fens, and tundra. Another subspecies, P. c. californicus (Vickery, 1967) was described from California.	en	Storozhenko, Sergey Yu. (2023): Orthoptera of Northeast Asia and Northwest America.

03C78784B257E315FF49FE04C962FD6E.taxon	discussion	Remarks. It is one of the most widespread Palaearctic species occurring from Atlantic to Pacific and also recorded from Beringia (North-Eastern Yakutia, Magadan region and Kamchatka). It inhabits open areas in larch forests and burned-out forests.	en	Storozhenko, Sergey Yu. (2023): Orthoptera of Northeast Asia and Northwest America.

03C78784B254E316FF49FC31C9B6FB73.taxon	discussion	Remarks. This species is widespread grasshoppers, occurring from Canada to the United States southwest to Oklahoma and Colorado. All known records from the Northwest Territories are either east of the Mackenzie River or near the Alberta border.	en	Storozhenko, Sergey Yu. (2023): Orthoptera of Northeast Asia and Northwest America. Zootaxa 5264 (4): 564-578, DOI: 10.11646/zootaxa.5264.4.6, URL: http://dx.doi.org/10.1094/PDIS-04-22-0755-PDN
03C78784B254E316FF49FF5DCA8BFDDF.taxon	discussion	Remarks. A few specimens of this species have been recorded from Yukon, the Northwest Territories and Alaska as S. lineatum Scudder, 1863 (Vickery & Kevan, 1983). Recently the specimens from Alaska were correctly identified as S. grossum (Haberski et al., 2021). The records of isolated populations of S. lineatum from the extremely North Canada seem to be result of misidentification and belong to S. grossum. In Beringia, this Holarctis species has been recorded from Northeast Yakutia, Magadan region, Alaska, Yukon, and the Northwest Territories. This large and conspicuous grasshopper inhabits wetlands.	en	Storozhenko, Sergey Yu. (2023): Orthoptera of Northeast Asia and Northwest America.

03C78784B254E316FF49FADECD8FF9B5.taxon	discussion	Remarks. This species is not found in Alaska and Yukon, in the Northwest Territories it only found along the Mackenzie River and Great Bear Lake. The nominotypical subspecies is replaced in southern Canada and the northwestern United States by T. v. suffosa Scudder, 1876. This species prefers exposed rocky or gravelly places.	en	Storozhenko, Sergey Yu. (2023): Orthoptera of Northeast Asia and Northwest America. Zootaxa 5264 (4): 564-578, DOI: 10.11646/zootaxa.5264.4.6, URL: http://dx.doi.org/10.1094/PDIS-04-22-0755-PDN
03C78784B254E316FF49FDB2CB8EFC59.taxon	discussion	Remarks. This species is endemic to eastern Alaska, southwestern Yukon, and the delta of Mackenzie River in the Northwest Territories. In the vicinity of Kluane Lake it was found on the edges of aspen forest and sagebrush steppe at altitude 800 – 1250 m (Berman et al., 1995). The life cycle of this species lasts for two years. The eggs deposited by females do not hatch until the following spring. The progeny spends the next winter as nymphs and reach maturity in the following summer (Vickery & Kewan, 1983).	en	Storozhenko, Sergey Yu. (2023): Orthoptera of Northeast Asia and Northwest America.
