5872 Camel Cricket
A kind of cricket with outsized antennae. Probably in Regina. No notes on that day. Saskatchewan, Canada. 8 August 2022
Genus Ceuthophilus
Other Common Names
Camel Cricket (usually applied to this genus), Cave Cricket (this and related genera)
Numbers
Nearctica.com lists 89 species; most diverse rhaphidophorid genus in North America.
Range: Canada through to Mexico
Habitat: Caves, basements, crawl spaces, outdoor closets.
Food: Reported to be scavengers. bugguide.net/node/view/24633
This individual lacks any prominent projections in between the antennal bases, which excludes Pristoceuthophilus (found mainly in BC) and Tachycines (which have quite long legs and cerci relative to body size compared to Ceuthophilus). The only other genus of camel crickets possible is Udeopsylla and those are quite distinctly robust, stocky and rust coloured with a very long pronotum. Identification to species often required clear and close views of the posterior abdomen, so many observations may have to rest at the genus level. For a great resource on identifying Orthoptera, including dichotomous keys, see Vickery and Kevan 1985 Insects and Arachnids of Canada, Part 14:
