Identification

Distinguished from other Ceuthophilus by the conical shape of the terminal abdominal structures ( or related structures), as indicated by the epithet. Separation from the Asian camel cricket (Diestrammena spp.) requires examination of body proportions and antennal characteristics. Identification to species level within Ceuthophilus typically requires examination of male genitalia and female ovipositor shape. The specific epithet 'conicaudus' (cone-tailed) provides the primary diagnostic feature separating this species from .

Appearance

are wingless with a characteristic humpbacked (camel-like) . The body is elongated with exceptionally long that exceed body length. The name 'conicaudus' indicates a conical or cone-shaped terminal abdominal structure. Legs are long and adapted for jumping, with the hind legs particularly enlarged. Body coloration is typically pale to brownish, providing camouflage in dim environments. Females possess a blade-like ovipositor protruding from the .

Habitat

Inferred from characteristics: cool, damp, dark microhabitats including caves, cellars, mine shafts, rodent burrows, and forest floor debris. Moisture-dependent; requires high humidity. May occur in subterranean or deeply shaded rocky .

Distribution

Recorded from Oklahoma and North America generally. Distribution details are sparse; precise range boundaries undocumented.

Seasonality

Nocturnally active year-round in suitable . Activity peaks during warmer months when foraging increases. Home invasion patterns, if occurring, would follow late summer to early autumn as with related .

Diet

scavenger. Consumes decaying organic matter including leaf litter, roots, fruits, and fungi. Captures and eats injured or weakened insects and . Has been observed feeding on mold, mildew, and paper products in human structures.

Life Cycle

Hemimetabolous development with , nymph, and stages. Eggs deposited in soil using the female's blade-like ovipositor. Nymphs resemble smaller, sexually adults. Multiple instars occur before maturity. Specific developmental timing undocumented.

Behavior

. Highly mobile; capable of jumping several feet when disturbed. Exhibits thigmotaxis, traveling with body contact against walls or surfaces. Non-social but aggregates in favorable microhabitats. (voluntary leg loss) has been observed in related when captured by . Does not produce sound (wingless, no stridulatory apparatus).

Ecological Role

Scavenger and in cave and forest floor . Contributes to decomposition of organic matter. Serves as prey for cave-dwelling including spiders, , and small mammals. Nutrient cycling in subterranean where other decomposers may be scarce.

Human Relevance

Occasional nuisance when entering basements, crawl spaces, or outbuildings. Does not bite humans or transmit . Rarely damages property; may nibble fabrics, paper, or stored goods. Fecal deposits can stain surfaces. Presence may indicate excess moisture or fungal growth in structures. Some anglers use camel crickets as fish .
