This picture is from my photo archives. This golden silk orb-weavers was hanging in the back of my house.


Kingdom: Animalia
Phylum: Arthropoda
Class: Arachnida
Order: Araneae
Suborder: Araneomorphae
Family: Nephilidae
Genus: Nephila (golden silk orb-weavers)
Species: N. maculate (the largest of this genus)
Common Names: golden silk orb-weavers, giant wood spiders or banana spiders, แมงมุมใยทองลายขนาน


The golden silk orb-weavers (genus Nephila) are a genus of spiders noted for the impressive webs they weave.

Nephila consists of numerous individual species found around the world. They are also commonly called golden orb-weavers, giant wood spiders or banana spiders.

In North America, the golden silk orb-weavers are sometimes referred to as writing spiders due to occasional zigzag patterns (stabilimenta) built into their webs, though these occur much more frequently in the webs of Argiope, such as the St. Andrew's Cross spider

The name of the golden silk orb-weavers refers to the color of the spider silk, not the color of the spider itself.

Yellow threads of their web shine like gold in sunlight. Experimental evidence suggests that the silk's color may serve a dual purpose: sunlit webs ensnare bees that are attracted to the bright yellow strands, whereas in shady spots the yellow blends in with background foliage to act as a camouflage.

The webs of most Nephila spiders are complex, with a fine-meshed orb suspended in a maze of non-sticky barrier webs. As with many weavers of sticky spirals, the orb is renewed regularly if not daily, apparently because the stickiness of the orb declines with age. When weather is good (and no rain has damaged the orb web), subadult and adult Nephila often rebuild only a portion of her web. She will remove and consume the portion to be replaced, build new radial elements then spin the new spirals. This partial orb renewal is distinct from other orb-weaving spiders that usually replace the entire orb web.

Typically she first weaves a non-sticky spiral with space for 2-20 more spirals in between (the density of sticky spiral strands decreases with increasing spider size). When she has completed the coarse weaving, she returns and fills in the gaps. Whereas most orb-weaving spiders remove the non-sticky spiral when spinning the sticky spiral, Nephila leave it. This produces a "staff paper" effect when the orb is seen in the sun: groups of sticky spirals reflecting light with "gaps" where the non-sticky spiral does not reflect the light.

The circular-orb portion of a mature N. clavipes web can be more than three feet (1 meter) across, with support strands extending perhaps many more feet away. In relation to the ground, the webs of adults may be woven anywhere from eye-level upwards high into the tree canopy. The orb web is usually truncated by a top horizontal support strand, giving it an incomplete look.

Hello Jitti,
based on the thumbnail, you cannot imagine to see this Nephila so clear and sharp because of the disturbing bright dots.
Also, the web is shown very sharp.
Besst wishes, Peter

Hi Jitti

This is a very impressive shot of this gigantic orb spider.

I particularly love the details you managed to capture of the web showing the intricate patterns and even some of the zigzag stabilimenta are visible. The spider itself also show some lovely details with excellent exposure balance and colour management.

Good work MF and TFS.
