Natural Habitat

Common around buildings, sheds, garages, fences, and other sheltered outdoor or indoor spaces, especially in temperate regions.

Diet & Feeding

Predatory; captures flies, mosquitoes, wasps, and other small arthropods in a tangled cobweb, then immobilizes prey with silk and venom.

Behavior Patterns

Mostly nocturnal and sedentary, retreating into a silken nook by day. Females remain near their webs and produce protective egg sacs; adults may enter buildings seeking shelter.

Risks & Benefits

Its bite is uncommon and usually causes localized pain, redness, or swelling, though medical advice is warranted for severe or persistent symptoms. It is beneficial as a household pest predator; avoid handling it directly.
