Utah camel cricket
Ceuthophilus utahensis, the Utah , is a wingless orthopteran in the Rhaphidophoridae. The is native to western North America, with documented occurrences in Colorado, New Mexico, and Utah. Like other camel crickets, it is adapted to dark, moist microhabitats. The species was described by Thomas in 1876.

Identification
Distinguished from true crickets (Gryllidae) by complete absence of wings and lack of sound-producing structures. Differs from Asian camel crickets (Diestrammena spp.) by native status and geographic range. Specific identification within Ceuthophilus requires examination of genitalic structures and other morphological details not reliably determined from photographs.
Habitat
Occupies cool, damp, dark microhabitats including caves, rock crevices, rodent burrows, and similar sheltered environments. In human-modified landscapes, may occur in basements, cellars, crawl spaces, and sheds where humidity is elevated.
Distribution
Documented from Colorado, New Mexico, and Utah in western North America. GBIF records indicate occurrence in these three states; precise range boundaries remain poorly defined.
Seasonality
Activity patterns not specifically documented for this . Related Ceuthophilus species are primarily , with increased home invasion activity reported in late summer and early autumn.
Diet
scavenger. Consumes decaying organic matter including leaves, roots, and fruits. Has been observed to feed on rotting remains of other insects and , including conspecifics. May occasionally damage paper products and stored fabrics.
Life Cycle
Developmental stages include , nymph, and . Females use the ovipositor to insert eggs into soil or substrate. Detailed information specific to C. utahensis is not available.
Behavior
. Exhibits thigmotaxis (traveling with body contact against walls or surfaces). Capable of (voluntary leg detachment) when threatened by . Can jump several body lengths when disturbed.
Ecological Role
Scavenger in cave and subterranean . Contributes to decomposition of organic matter. Serves as prey for various in dark systems.
Human Relevance
Occasional nuisance in basements and crawl spaces. Not dangerous to humans; does not bite or sting. Fecal deposits may stain surfaces in heavily infested structures. Can be excluded by reducing humidity and sealing entry points.
