Giant Golden Orbweaver (Nephila pilipes) lives in tropical forests across Southeast Asia. It feeds on flies and insects. Its conservation status is Least Concern.
Fascinating facts about the Giant Golden Orbweaver
- Adult females are very large, with a body length of 25 to 50 mm (1 to 2 inches). Males are dwarfs, measuring only 4 to 6 mm (about 0.2 inch). In N. pilipes, female spiders are much larger than their male counterparts, males can be 4-10 times smaller than the females.
- Females keep growing after they're sexually mature, a rarity among spiders. Female N. pilipes spiders are able to achieve a large size because they can continue to molt and grow after maturity. This extra growth lets them lay more eggs. Meanwhile, tiny males race to locate wandering females, because the first male to find a moving female often fertilizes a greater share of her eggs. The split strategy, giant, fecund females and sprint-ready dwarf males, maximizes each sex's chance to pass on genes.
- Golden orb-weavers thrive from tropical rainforests to dry shrublands, spanning more than twenty countries across Asia and Oceania. It can be found in Japan, China, Vietnam, Cambodia, Taiwan, Malaysia, Singapore, Myanmar, Indonesia, Thailand, Laos, Philippines, Sri Lanka, India, Pakistan, Nepal, Papua New Guinea, and Australia. To stay cool, they tilt their bodies when it hits 32 °C (90 °F), aligning the abdomen toward the sun while keeping the cephalothorax parallel to the web. If heat climbs above 40 °C (104 °F), they abandon the web entirely, protecting themselves from lethal overheating.
- Their webs can span up to a meter across, yet a torn section is mended in under an hour. For adult Nephila spp., their webs are typically 0.5-1.0 m in diameter. When their webs are partially damaged, it usually takes N. pilipes 10-60 minutes to repair the web.
- Spiderlings hitch rides on the wind, but only when the breeze is strong enough to lift them. Research conducted in lab has found that N. pilipes will display ballooning behavior when the wind speed reaches a threshold of 3.17 m/s. This precise wind-speed trigger helps them colonize new trees, islands, and even distant coastlines, explaining why the species is found across such a wide geographic swath.
