Tree trapdoor spiders

Family Migidae

Tree Trapdoor, Migidae, Migas, with door

Identification

Tree trapdoor spiders resemble the Saddle-legged Trapdoors but are much smaller and build very short tubes on trees or in the ground.

Diversity & distribution

Three genera (Migas, Heteromigas and Moggridgea) and several species are known from Australia.

Like the Idiopidae, the family occurs also in Africa, Madagascar, New Zealand and South America but is not yet recorded from India. In Australia, they are found in coastal regions (usually only in rainforest) of the eastern states, including Tasmania, as well as relict areas in south-western Australia and small southern areas in South Australia.

Notes

These are very rare spiders with the camouflage of the burrow protecting them against most predators except Lacewings (family Mantispidae).

Some Modern spiders, Wolf Spiders, also build thin doors that are often detachable; these species tend to occur west of the Great Divide.
