Golden Silk Orb-Weaver, Golden Silk Spider, Banana Spider
Nephila clavipes
Tetragnathidae (Long-jawed Orb-Weavers), Order Araneae. Note: Formerly placed in Nephilidae or Araneidae. Characterized by elongated bodies, long legs, and building large, symmetrical orb webs with yellow-tinted silk.
Physical Description
Elongated body shape with a distinctively long, cylindrical abdomen and slender legs bearing characteristic tufts of hairs. Exhibits extreme sexual dimorphism, with females being exceptionally large compared to the dwarf males.
Size Estimate
Female body length typically 24-40 mm with a leg span reaching up to 10-12 cm. The visible specimen appears to be an adult female hanging in her characteristic large orb web.
Coloration & Markings
Features a mix of yellow, reddish-brown, or dark brown coloration on the body, with contrasting yellow and black banding on the legs. The silk itself has a distinct golden sheen.
Web Type
Large, vertical orb web constructed from strong, yellowish silk. Often built high between trees or structural elements, featuring a dense, non-sticky central hub where the spider hangs head-down.
Eye Arrangement
Eight small eyes arranged in two rows, set closely together on a raised cephalic tubercle typical of the family, providing moderate visual acuity.
Leg Characteristics
Long, slender legs with prominent tufts of stiff hair (brush-feet) on the tibia and metatarsus, often held in pairs. Marked with dark and light bands.
Venom & Safety Information
Venom Information
Contains neurotoxic components tailored for paralyzing invertebrate prey. It is relatively weak and generally harmless to larger animals and humans.
Medical Significance
Not medically significant. A bite may cause minor, localized pain, redness, or swelling similar to a mosquito bite, but they rarely bite unless heavily provoked or squeezed.
Safety Recommendations
Simply admire from a safe distance. Avoid walking face-first into their large webs by watching for lines in wooded areas. If found near a high-traffic walkway, gently relocate using a stick or broom.
Habitat & Behavior
Habitat & Range
Found throughout the southeastern United States, Central America, the Caribbean, and parts of South America. Prefers humid, wooded habitats, forest edges, and gardens where structural supports allow large web construction.
Behavior & Temperament
Docile and non-aggressive toward humans. Spiders remain stationary at the center of their large webs during the day and night, waiting for prey to impact the sticky spirals.
Diet & Prey
Generalist predator feeding primarily on flying insects such as mosquitoes, flies, beetles, moths, and occasionally small wasps or butterflies caught in the orb web.
Seasonal Activity
Most active and visible during the warm summer and autumn months, with females reaching peak size and maturity just before laying eggs in the fall.
Description
The Golden Silk Orb-Weaver is one of the most majestic and easily recognized spiders in its range, famous for its impressive size, striking yellow-and-black coloration, and massive webs of shimmering golden silk. Hanging patiently at the center of its geometric masterpiece, this expert architect plays a vital role in controlling flying insect populations in woodland and garden ecosystems.
Key Features
Extremely large, elongated cylindrical abdomen, long banded legs with distinct hair tufts, and a massive vertical orb web constructed of noticeably yellow-tinted silk.
Similar Species
Argiope aurantia (Yellow Garden Spider), which features a wider, oval-shaped abdomen with jagged yellow and black markings rather than a cylindrical body and golden silk.
Life Cycle
Females construct brownish, papery egg sacs containing hundreds of eggs in late autumn, hidden beneath bark or leaf litter. Spiderlings hatch in spring, disperse via ballooning, and mature through multiple molts within a single year.
Ecological Importance
Serves as an apex invertebrate predator in its microhabitat, regulating populations of pest insects and serving as a food source for birds and small mammals.
Conservation Status
Not evaluated by the IUCN, but populations are generally stable and widespread throughout their natural geographic range.
Interesting Facts
The golden coloration of the silk provides camouflage among sunlit foliage and acts as a natural UV trap for attracting prey. Their silk is also remarkably strong and elastic, inspiring ongoing biomimetic research.
Photography Tips
Backlighting the web during early morning or late afternoon makes the golden silk glow brilliantly. Use a macro lens for close-ups of the spider or a wider angle to capture the massive scale of the web.
