Common name: Native Bush Cockroach,
These small cockroaches are NZ natives. They are found in logs and leaf litter, under loose bark. Most of the species favours damp, dark habitats. They are not a household pest. They are usually introduced into a house usually by firewood. They are omnivorous and may feed on all sorts of organic materials. They can even eat dead wood, which they digest with the help of symbiotic gut flora.
The species Celatoblatta quinquemaculata can be found under slabs of rock in the subalpine and alpine regions of New Zealand. It is unusual because it survives through freezing conditions by allowing the water within its body to freeze and as temperature rises they become active.
