Cave crickets have very large hind legs with "drumstick-shaped" femora and long, slender antennae. They are brownish in color and rather humpbacked in appearance, always wingless, and up to two inches/5 cm long in body and 10 cm (4 inches) for the legs. As the name implies, cave crickets are commonly found in caves. However, most species live in other cool, damp situations such as in wells, rotten logs, stumps and hollow trees, and under damp leaves, stones, boards, and logs. Some reach into into alpine areas and live close to permanent ice — the Mt Cook "flea" and its relatives in New Zealand. The group known as "sand treaders" are restricted to sand dunes, however, and are adapted to live in this environment; they are active only at night, and spend the day burrowed into the sand, to minimize water loss. They are pale, sand-colored insects, and their legs are modified with strong bristles for rapid digging. In the large sand-dunes of California and Utah they serve as food for scorpions.

Their distinctive limbs and antennae serve a double purpose. Typically living in a lightless environment, or active at night, they rely heavily on their sense of touch, which is limited by reach. While they have been known to take up residence in the basements of buildings, many cave crickets live out their entire lives deep inside actual caves. In those habitats they sometimes face long spans of time with insufficient access to nutrients. To avoid starvation, they have been known to devour their own extremities, even though they cannot regenerate limbs. Given their limited vision, cave crickets will often jump towards any perceived threat in an attempt to frighten it away. Their large hind legs allow them to jump high and far
