See this bug in the Encyclopedia

Natural Habitat

Typically found on the ground in leaf litter, under rocks, or on various surfaces in woodlands and gardens where ants are present.

Diet & Feeding

Strictly carnivorous; they primarily eat small insects and other spiders.

Behavior Patterns

These spiders exhibit 'Batesian mimicry,' where they mimic the physical appearance and erratic walking movements of ants to avoid predators that find ants unpalatable. They are active hunters that do not spin webs to catch prey.

Risks & Benefits

They are beneficial to the ecosystem as they help control pest insect populations. They are not considered dangerous to humans; while capable of biting if handled, their venom is not medically significant.
