In Papua New Guinea, a diverse range of spiders can be found, but 2 common ones stand out: the Giant Golden Orbweaver and the Gray Wall Jumping Spider. The Giant Golden Orbweaver, characterized by its stripy yellow and black coloring, builds its webs in dense rainforests and jungles, preferring habitats with no direct sunlight. Despite its intimidating appearance, it poses no threat to humans. On the other hand, the Gray Wall Jumping Spider, with its flattened torso and short, thick greyish-white hair, is known for its exceptional jumping ability and the clicking noises it makes during courtship. These spiders, although often misunderstood, play a crucial role in controlling the insect population and maintaining the balance of ecosystems in Papua New Guinea.

Giant Golden Orbweaver Nephila pilipes

Identifying Characteristics

The Giant Golden Orbweaver, scientifically known as Nephila pilipes, is a stunning spider species commonly found in Papua New Guinea. The female Giant Golden Orbweavers can grow to be around 30-50 mm (1.1-1.9 in) in size, while their overall size, including their legs, can reach up to 20 cm (7.9 in). On the other hand, the males are significantly smaller, measuring only 5-6 mm (0.19-0.23 in) in length. These spiders have a distinctive coloring, featuring a stripy yellow and black pattern with black legs and lighter-colored joints.

Habitat and Behavior

Giant Golden Orbweavers thrive in habitats with minimal direct sunlight. This preference makes them perfectly suited to live in dense rainforests and jungles. They construct intricate webs in bushes and trees near water sources, where they patiently await their prey. These spiders are known for their impressive web-building skills, creating large, circular webs that can span several feet in diameter. The webs are typically suspended between branches or vegetation, providing the perfect trap for flying insects.

Diet and Feeding Habits

Although the Giant Golden Orbweaver appears intimidating, it primarily feeds on a select few species of insects. Interestingly, if an insect species is not on its preferred menu, the spider will simply discard it from its web without consuming it. To ensure a steady supply of its favored food source, the Giant Golden Orbweavers often store desirable prey in their webs for later consumption. This behavior not only guarantees their survival but also helps regulate the local insect population.

Safety for Humans

Despite their formidable appearance, Giant Golden Orbweavers pose little threat to humans. Bites from these spiders are rare, and even when they occur, the symptoms are usually mild. Individuals who experience a bite may experience muscle soreness or tightness, but these symptoms typically resolve on their own without the need for medical intervention. It is important to note that while the Giant Golden Orbweaver is generally harmless, anyone who may have a severe allergic reaction to spider bites should seek medical attention immediately.

Gray Wall Jumping Spider Menemerus bivittatus

Identifying Characteristics

The Gray Wall Jumping Spider, known scientifically as Menemerus bivittatus, is another spider species commonly found in Papua New Guinea. This particular spider exhibits a flattened torso and is adorned with short, thick, greyish-white hair. Tufts of dark brown hair grow near their eyes. Males of the species possess a brownish-white stripe on each side of the abdomen, as well as a black dorsal stripe. Females, on the other hand, have larger abdomens and are typically lighter brown. Additionally, their abdomens are rimmed with broad black stripes that converge at the end. Both males and females measure approximately 9 mm (0.3 in) in length, with males usually being slightly smaller.

Habitat and Behavior

The Gray Wall Jumping Spider is native to Papua New Guinea but has since spread to other parts of the world. These spiders can often be found on the exteriors of buildings or clinging to tree trunks in gardens. Their exceptional ability to jump enables them to swiftly move between surfaces and catch their prey with ease. Gray Wall Jumping Spiders possess wide eyes and excellent visual acuity, allowing them to track and target their victims. Their stalking technique involves patiently observing their prey before pouncing for a quick and decisive attack.

Hunting Techniques

Unlike many other spider species that rely on webs to capture prey, Gray Wall Jumping Spiders employ their remarkable agility and jumping ability to secure their meals. With their sharp eyesight, they can accurately estimate the distance and position of their target, and when the opportunity arises, they will spring forward in a swift and precise movement, overpowering their unsuspecting prey. This hunting technique allows them to effectively control insect populations, contributing to the natural balance of ecosystems.

Courtship Behavior

Male Gray Wall Jumping Spiders exhibit fascinating courtship behavior. They produce clicking noises as part of their mating rituals, which are intended to attract females. These sounds are created by the hairs on their femurs and the teeth on their chelicerae, small claws located at the front of their mouths. Although these sounds are too low and quiet for humans to hear, they are a crucial aspect of the spider’s reproductive behavior. While the clicking noises may be a bit eerie to imagine, they serve as an important form of communication for these spiders.

Other Spider Species in Papua New Guinea

Papua New Guinea is home to numerous spider species, and the Giant Golden Orbweaver and the Gray Wall Jumping Spider are just two examples of the rich diversity of arachnids found in the region. Due to the sheer number of spider species in Papua New Guinea, it is impossible to provide an exhaustive list. Estimates suggest that there are over 50,000 different kinds of spiders worldwide, with the potential for more discoveries to be made. As such, it is essential to recognize that the spiders discussed in this article are merely a fraction of the multitude of spider species living in Papua New Guinea.
