Scientific Classification

Giant Wood Spider

Physical Description and Identification 

Adults

  • Size: Sexual dimorphism is seen when it comes to size as the females are excessively large (30 mm to 50 mm), and the males are considerably small (5mm to 6mm). The reason for the large size of the female Nephila Pilipes is that even after attaining maturity, molting continues.
  • Color: Male– Light brown or red; Female-Yellow; Both sexes have black legs with yellow bands, prominent near the area of their joint.
  • Other Characteristic Features: They have a cylindrical-shaped elongated body alongside long legs. The abdomens of the female have the appearance of a globe when the eggs are inside.

Eggs

The eggs are contained in a sac which is kept in a pit covered with soil or leaves, instead of being placed in the web. A particular sac contains about 2000 eggs.

Spiderlings

When they are juveniles, their legs (first, second, fourth pairs) are hairy which disappears on maturation.

Giant Wood Spiderling

The Web

These spiders produce golden silk for weaving their web, which is vertical with an irregular mesh, having a height and width of 6mm and 2mm respectively. They do not dismantle their webs often and it can last for a couple of years.

Are Giant Wood Spiders Venomous?

Yes, Giant Wood Spiders have venom. They use it mainly for catching their prey. However, their venom isn’t usually harmful to humans.

Can Giant Wood Spiders Bite?

Giant Wood Spiders can bite if they feel cornered or threatened. The bite might sting a bit, but it’s typically not a big concern for most people.

Ecological Importance and Behavior of Giant Wood Spider

Nephila Pilipes plays a pivotal role in maintaining ecological balance. They are proficient hunters, primarily preying on small insects, which helps in controlling the population of these pests in their habitat. The females exhibit maternal instincts, meticulously guarding their egg sacs until the spiderlings are ready to venture out.

Natural Predator: Birds, wasps, and damselflies stand as the common predators of the Nephila Pilipes. These predators pose a constant threat, particularly to the young spiderlings and juveniles, necessitating constant vigilance and agility from the spiders to ensure their survival.

Prey-Predator Dynamics: The relationship between the giant wood spider and its predators is a complex dance of survival. The spider’s web not only serves as a trap for its prey but also acts as a line of defense against its predators. The Nephila Pilipes must constantly balance its role as a predator with its vulnerability as prey, showcasing the intricate intricacies of nature’s food web.

Relationship with Humans: Humans share a unique relationship with the Nephila Pilipes. While some may view them as pests, others appreciate their role in pest control and their contribution to biodiversity. In some regions, such as Vietnam’s Bình Thuận Province, they even find their way into local cuisine, where the Raglai people are known to roast and consume them.
