Natural Habitat

Found in lawns, gardens, and woodlands. They live in underground burrows lined with silk, often topped with a hinged "door" made of soil and vegetation.

Diet & Feeding

Carnivorous. They eat insects and other arthropods, such as crickets, beetles, and occasionally smaller spiders.

Behavior Patterns

Nocturnal and solitary hunters. They wait behind their trapdoor for prey to pass by, then lunge out to grab it. Males are most frequently seen above ground when searching for mates.

Risks & Benefits

Generally harmless to humans. While they can bite if provoked, their venom is not considered medically significant for people. They benefit the ecosystem by controlling insect populations.
