Hadenoecus cumberlandicus,[1] the Cumberland cave cricket, is a species of camel cricket in the family Rhaphidophoridae. It is found in North America.[2][3][4]

Habitat

The Cumberland cave cricket aggregates into groups or clusters within cave wall recesses and is considered vital to cave community ecosystems, noted as a keystone species.[5]

Features and reproduction

The crickets aggregate to minimize dehydration using specialized pheromones that reduce mobility on contact, acting as an anti-predator defense tactic from cave spiders. It has been found to have a co-occurrence relationship with the cave orb weaver spider Meta ovalis. Some populations of H. cumberlandicus are parthenogenic.[6]

Identification

This cricket has very long legs, and a dark body. Its body is broken into scale sections. The antennae are also longer than that of an average camel cricket.[7]
