They may be called trapdoor spiders, as are other, similar species, such as those of the families Liphistiidae, Barychelidae, and Cyrtaucheniidae, and some species in the Idiopidae and Nemesiid
Trapdoor spider is a common name that is used to refer to various spiders from several different groups that create burrows with a silk-hinged trapdoor to help them ambush prey. Several families within the infraorder Mygalomorphae contain trapdoor spiders: Actinopodidae, a family otherwise known as 'mouse-spiders', in South America and Australia
Each burrow has two or three entrances that lead into a main tube. The trapdoor is a form of safety and ways of ambushing prey. Idiopidae adapt and live in many various environments as seen by the map on the far right, which leads to the various species to co-exist with other Idiopidae and other spiders outside of the family.

Like other trapdoor spiders, Eucteniza species construct burrows in the ground with a hinged lid, from which they wait to ambush passing prey. Burrows and prey have been studied in E. relata, and other species are believed to have similar behavior. The burrow consists of an un-branched tube, lined with silk and soil, ranging from 7 to 25 cm (2. ...
