Golden Silk Orb-weaver, Banana Spider, Writing Spider
Trichonephila clavipes
Araneidae (Orb-Weavers) / Nephilidae, Order Araneae
Physical Description
Elongated cylindrical abdomen with a silvery-white to greyish carapace covered in tiny hairs. Highly pronounced sexual dimorphism, with females being massive compared to tiny males.
Size Estimate
Female body length 24–40 mm (1–1.5 inches), with a leg span often reaching 100–125 mm (4–5 inches). The specimen shown is a fully mature adult female.
Coloration & Markings
Abdomen is olive-green to dull orange-yellow with characteristic light yellow-white spots. Carapace is silver-grey. Legs are yellowish brown with distinctive dense black hair tufts (gaiters) on the joints.
Web Type
Large, persistent golden-tinted orb web, often spanning over 1–2 meters wide, featuring a vertical zigzag or silk line debris banner above or below the hub.
Eye Arrangement
Eight eyes arranged in two rows of four, with small median eyes clustered and lateral eyes positioned further apart on small humps.
Leg Characteristics
Long, thin, banded legs with conspicuous dark brush-like tufts of setae on the femora and tibiae of legs I, II, and IV.
Venom & Safety Information
Venom Information
Mildly neurotoxic venom meant to paralyze small insect prey. Not dangerous to humans.
Medical Significance
Harmless/Low medical concern. Bites cause localized pain, minor swelling, and redness similar to a mild bee sting that subsides within hours.
Safety Recommendations
Leave the spider undisturbed in its web. If relocation is needed, use a broom handle or stick to move the support lines gently to nearby vegetation.
Habitat & Behavior
Habitat & Range
Southeastern United States (including coastal South Carolina and Georgia, such as Hilton Head Island), Central America, and South America. Prefers warm, humid environments, coastal forests, swamps, and garden areas near structures.
Behavior & Temperament
Docile and non-aggressive, resting head-down in the center of its web. Highly hesitant to bite unless directly squeezed or mishandled.
Diet & Prey
Flying insects including flies, mosquitoes, beetles, wasps, moths, and stink bugs. Larger females can occasionally entrap small dragonflies or cicadas.
Seasonal Activity
Peak activity and maturity occur in late summer to autumn (August through October) in southern coastal regions.
Description
Trichonephila clavipes is one of the largest non-tarantula spiders in North America, famous for its glowing yellow-gold web silk and brushed legs. It sits prominently at the center of its expansive golden web during late summer and autumn.
Key Features
Elongated olive/yellowish spotted abdomen, bright silver-white carapace, dark brush-like leg hair tufts, and golden silk web.
Similar Species
Trichonephila clavata (Joro Spider) which has distinct red markings and yellow-black stripes; Argiope aurantia (Yellow Garden Spider) which has a black-and-yellow patterned carapace and non-golden web silk.
Life Cycle
Females lay several egg sacs containing hundreds of eggs wrapped in yellow silk in autumn. Females die in late fall, and spiderlings emerge in spring.
Ecological Importance
Acts as an exceptional biological pest controller, snaring vast numbers of flying pests, agricultural bugs, and mosquitoes.
Conservation Status
Not evaluated (IUCN), but abundant and stable throughout its native range.
Interesting Facts
Its golden silk is remarkably strong, tensile-wise comparable to Kevlar, and has been researched for use in bio-engineering and textiles.
Photography Tips
Photograph from a side angle with backlighting or morning light to highlight the shimmering golden silk and distinctive brushed legs.
