The Nocticolidae is a small family of cockroaches and many of these live in caves or other subterranean habitats. They are often cave adapted, i.e. lack eyes and/or wings, have a light colouration and comparatively long legs. A single genus, Nocticola, occurs on continental Australia, with Metanocticola occuring on Christmas Island only.
