It is typically found in dark, damp outdoor environments such as under bark, logs, or stones. 2. An insect known for its jumping ability: It is named for its capacity to make sudden, erratic jumps when disturbed, propelled by a spring-like mechanism in its abdomen, and for the three long, bristle-like appendages (cerci) at the tip of its abdomen.
