[2] Rather than egg sacs being hung in the web, a pit is dug which is then covered with plant debris or soil.

It has been reported that this sharp contrast between yellow and black color can increase foraging success towards visually-oriented prey.

N. pilipes display sexual dimorphism, the presence of distinct difference between the males and females of a species.

This claim is supported by a study on N. pilipes' relative Trichonephila clavata, in which males highly prefer females that molt recently.

[10] Additionally, female gigantism would have been important to the ancestral species at the time when mating plugs were still effective, as body size has been shown to increase fecundity.

[7] Female N. pilipes spiders are able to achieve a large size because they can continue to molt and grow after maturity.

Female N. pilipes spiders will stop molting, however, during times of high copulation where it may not be advantageous to continue to grow as sperm are fertilizing eggs.

[5] Alternatively, sexual size dimorphism may have evolved due to selection favoring male dwarfism instead of female giganticism.

An explanation of how dwarfism was selected for is due to scramble competition in which smaller male size is advantageous for reproduction.

It can be found in Japan, China, Vietnam, Cambodia, Taiwan, Malaysia, Singapore, Myanmar, Indonesia, Thailand, Laos, Philippines, Sri Lanka, India, Nepal, Papua New Guinea, and Australia.

However, reports show that N. pilipes can be found in dry sclerophyll and low shrublands, hundred miles away from the coast.

will adjust the angle between its body and the incoming sunlight, orienting its abdomen towards the sun but keeping the cephalothorax parallel to the web.

When temperature further rises, it will align the full body along the sunlight direction, further reducing the area that is receiving heat from the sun.

[6] It has been reported that some N. pilipes can adjust the ultraviolet radiation reflected by stripes on their body to attract preys that are UV light oriented.

[4][13] The bands on the legs and body of N. pilipes can reflect UV radiation, so they are more visible to flying insects.

[14] The web constructed by N. pilipes has elastic silk at the center to absorb the kinetic energy of moving insects.

[14] It has been reported that N. pilipes can adjust their silk composition, responding to different diet and environmental conditions.

[15] When N. pilipes are fed with flies, small and airborne prey, the silk becomes more elastic, and the mesh size becomes smaller.

Females, on the other hand, tend to be reluctant to mate repeatedly and only select those males with good genes.

[17] Unlike other close relatives, N. pilipes have a less aggressive mating ritual, and sexual cannibalism is very rare.

[6] Males have evolved a mechanism called mate binding to avoid females' resistance and cannibalism.

[17] Males can deposit silks soaked with sexual hormones onto the female's body to calm the tactile and chemical receptors.

The eggs are always found beneath leaves or other shades, which prevent direct UV light from the sun.

Female N. pilipes lay eggs in small pits on the ground to avoid predation and parasitism.

The primary enemy of N. pilipes in nature is the bird, which evolves to fly by and take them without being entangled by the web.

Its bites are likely similar to other orb-weaving spiders, which are reported to cause acute symptoms, including muscle pain, feeling of tightness, and reflexes exaggeration.

[19] Spiderlings can disperse via wind to larger areas after birth to avoid overcrowded habitat and competition for resources.

[19] 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.

[19] However, ballooning is subject to many influences in wild habitats, such as wind angles, humidity, temperature, and pressure.

[19] Raglai people in Vietnamese Bình Thuận Province consume N. pilipes after roasting them, and consider them to be a healthy food source.
