Golden orb-weaver (banana spider)
Trichonephila clavipes
- Order & Family
- Araneae; Nephilidae
- Size
- Adult females are about 2.5–4 cm (1–1.6 in) in body length, with legs spanning up to 10–12 cm (4–5 in); males are much smaller.
Natural Habitat
Warm, humid habitats including forest edges, gardens, woodland clearings, and shrubs across the southeastern United States, the Caribbean, and parts of Central and South America.
Diet & Feeding
It captures flying insects—especially flies, moths, bees, and wasps—in large golden, orb-shaped webs, then injects venom and consumes liquefied tissues.
Behavior Patterns
Females build large, strong webs and remain centrally positioned, often adding zigzag silk decorations. Tiny males may occupy the female’s web and mate cautiously; females produce silken egg sacs.
Risks & Benefits
Not medically significant to humans; bites are uncommon and typically cause only localized pain or irritation. It benefits ecosystems by controlling flying-insect populations and is generally nonaggressive.
