The Craggy Island Cricket (Cavernotettix craggiensis) is a small terrestrial cricket that occurs at several sites under boulders and in burrows of breeding seabirds on Craggy Island, which is a small rocky island about 20 km northwest of the tip of Flinders Island in Bass Strait (unallocated Crown land). The species is known only from collections made in 1972.
There are no immediately identifiable threats to the species. However, factors such as illegal collection, natural predation, climate change (and its impact on microclimate conditions), and stochastic events are all highlighted as possible threats.

Permit: A permit is required under the Tasmanian Threatened Species Protection Act 1995 to 'take' (which includes kill, injure, catch, damage, destroy and collect), keep, trade in or process any specimen or products of a listed species. Additional permits may also be required under other Acts or regulations to take, disturb or interfere with any form of wildlife or its products, (e.g. dens, nests, bones). This may also depend on the tenure of the land and other agreements relating to its management. ​​​​​
