Natural Habitat

Found in dark, damp areas such as basements, crawl spaces, caves, and under logs or rocks; often indoors in corners of walls and ceilings.

Diet & Feeding

Feeds on various insects and arthropods, such as flies, beetles, and moths, which it catches in its funnel-shaped web.

Behavior Patterns

Constructs flat, sheet-like webs with a funnel-shaped retreat on one side. They are nocturnal and are among the fastest-running spiders; males are more likely to be seen wandering in late summer/autumn searching for mates.

Risks & Benefits

They are beneficial to ecosystems and homeowners as they control pest insect populations. While they can bite if provoked, their venom is not considered medically significant to humans, and they are generally shy and non-aggressive.
