Common Cave-cricket

<em>Troglophilus cavicola</em>, commonly known as the common cave cricket, is an insect species adapted to subterranean and cave environments. It typically inhabits terrestrial and freshwater ecosystems, often associated with caves, rock crevices, and other sheltered underground habitats where stable humidity and temperature conditions persist year-round. The species is classified as Least Concern on the IUCN Red List, indicating that it is not currently facing significant conservation pressure globally. Common cave cricket belongs to the genus <em>Troglophilus</em> within the family Rhaphidophoridae. As a troglophile, it is capable of completing its life cycle both inside and outside cave environments, typically foraging at night for organic matter and small invertebrates. Biological traits such as average lifespan, body length, and mass of this species remain poorly documented in the scientific literature. Detailed geographic range and country-level distribution data are not currently available for this species, though it is associated with cave systems in European regions where suitable underground habitats exist.
