See this bug in the Encyclopedia

Natural Habitat

Webs occur in sheltered, undisturbed spots such as corners, undersides of containers, sheds, garages, and outdoor furniture.

Diet & Feeding

It captures flies, mosquitoes, small beetles, and other arthropods in a sticky, irregular cobweb, then immobilizes prey with silk and venom.

Behavior Patterns

This sedentary spider stays near the web’s retreat and detects vibrations through the silk. Females produce silk egg sacs and may remain near them; identification to species requires a clearer view of markings.

Risks & Benefits

Usually nonaggressive and beneficial as an insect predator. Bites are uncommon and typically cause localized pain, redness, and swelling, though medically significant symptoms warrant care.
