Remarks

"Trapdoor spiders" because they make their homes in tubelike burrows completely lined with silk. They cut a lid which is attached on one side, like a hinged trapdoor. The top of the lid is camouflaged with debris. When they feel the vibration of prey, they rush out to capture it, then return to the burrow. Females rarely leave their burrows, but males may be found wandering in search of prey.
