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.

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.
