See this bug in the Encyclopedia

Natural Habitat

Gardens, woodland edges, hedgerows, and vegetation near buildings across much of the Northern Hemisphere.

Diet & Feeding

Carnivorous; captures flies, moths, aphids, and other small arthropods in a sticky orb web, then immobilizes them with silk and venom.

Behavior Patterns

Builds or repairs a circular web, usually at dusk or dawn, and waits at its center or nearby for vibrations. Adults commonly mate in late summer; females produce an egg sac and die afterward.

Risks & Benefits

Venom is not medically significant to humans, and bites are rare, usually causing only brief local irritation. It benefits gardens by controlling flying insect populations.
