Natural Habitat

Sunny, sheltered vegetation such as gardens, meadows, forest edges, and vine-covered structures. It builds large orb webs among tall plants.

Diet & Feeding

It captures and consumes flying or jumping insects, including flies, moths, grasshoppers, and bees. Prey is wrapped in silk and externally digested.

Behavior Patterns

The spider typically hangs head-down at the web’s center, often with a conspicuous zigzag stabilimentum. Females mature in summer, produce egg sacs in fall, and die after laying eggs; young overwinter inside the sacs.

Risks & Benefits

It is nonaggressive and its bite is uncommon, usually causing only localized pain and irritation. It benefits gardens by reducing populations of many insect pests.
