Brush-footed Trapdoor Spider

Idiommata spp.

The Brush-footed Trapdoors are a genus of large, robust, and impressive mygalomorph spiders found across Australia. They are not considered pests in a conventional sense, but wandering males often cause alarm when they are found inside homes, especially in eastern Australia where they can be mistaken for the dangerous Funnel-web spider. These spiders are so-named for the dense tufts of hair on their feet which allow them to climb smooth surfaces, an unusual trait for a trapdoor. Females live a sedentary life in deep burrows, which may or may not have a trapdoor. Males leave their burrows to search for mates, which is when they are most commonly encountered by people.
