Natural Habitat

Commonly found in dark, undisturbed areas of buildings such as basements, attics, barns, and crawl spaces, where they build funnel-shaped webs.

Diet & Feeding

Insects and other small arthropods that become trapped in its funnel web, which it navigates quickly using sensory vibrations.

Behavior Patterns

Night-hunting predators that build flat mats of silk leading to a retreat funnel. They are timid and usually retreat into the funnel if they feel vibrations from a large intruder.

Risks & Benefits

Benefits the ecosystem by controlling indoor pests like flies and moths. They are not considered medically significant to humans, as their venom is weak and they rarely bite unless handled roughly.
