Yellow garden spider (black-and-yellow argiope)
Argiope aurantia
- Order & Family
- Araneae, Araneidae (orb-weaver spiders)
- Size
- Females are about 19–28 mm (0.75–1.1 in) in body length; males are much smaller, about 5–9 mm.
Natural Habitat
Sunny, open areas with tall vegetation, gardens, grasslands, and around buildings; it builds webs several feet above ground.
Diet & Feeding
It captures flies, grasshoppers, bees, and other flying or jumping insects in its orb web, then immobilizes them with silk and venom.
Behavior Patterns
Mostly active by day, it often rests at the web’s center in a zigzag silk pattern called a stabilimentum. Adults appear in summer and fall; females produce egg sacs before dying after the first severe frost.
Risks & Benefits
Venom is medically mild, and bites are uncommon, usually causing temporary local pain or swelling. It is beneficial because it naturally controls many garden and household insect pests.
