Trapdoor Spiders – Idiopidae

This family contains a variety of burrowing spiders live beneath the ground in silk-lined burrows. Some species build silk-hinged lids (trapdoors) on their burrows, while other have open lidless entrances. Most of these spiders are stocky in build and are dark earthy colours and as a result of often confused with funnel-web spiders,  although they are generally lighter in colour than the glossy black funnel-webs, or have more hair on the cepahlothorax than their more venomous cousins.  While the spiders in this group have large fangs they are not regarded as dangerous.
