Natural Habitat

Gardens, shrubbery, woodland edges, parks, and other vegetated areas; commonly builds webs between plants or structures.

Diet & Feeding

A predator of flying insects, including flies, moths, mosquitoes, and small wasps. It captures prey in its orb web, then immobilizes it with silk and consumes it externally digested.

Behavior Patterns

Builds a large, geometric orb web and often rests at its center or in a nearby retreat connected by signal threads. Adults mature in late summer and autumn; egg sacs overwinter, while adults usually die after reproduction.

Risks & Benefits

Nonaggressive and generally harmless to people; bites are rare and typically minor. It provides valuable natural pest control by reducing flying-insect populations.
