The Six Spotted Fishing Spider, scientifically known as Dolomedes tenebrosus, is a fascinating arachnid that belongs to the family Pisauridae. This species is native to North America, specifically found in the eastern and central regions, and is known for its impressive hunting abilities and unique characteristics. The Six Spotted Fishing Spider is a relatively large spider, with a body length that can range from 0.75 to 1.25 inches (1.9 to 3.2 cm) and a leg span of up to 3 inches (7.6 cm).
Physical Characteristics and Habitat
The Six Spotted Fishing Spider has a brown or grayish-brown body with six distinct white spots on its abdomen, which gives it its common name. The spots are often arranged in a specific pattern, with two spots on either side of the abdomen and two spots in the middle. The spider’s body is also covered with fine hairs, which help to detect vibrations and prey. The Six Spotted Fishing Spider inhabits areas near water, such as ponds, lakes, and slow-moving streams, where it can be found walking on the surface of the water or hiding in vegetation.
Hunting Behavior and Diet
The Six Spotted Fishing Spider is an active hunter that feeds on a variety of aquatic insects, including mosquitoes, flies, and beetles. It uses its excellent eyesight and sensitive hairs to detect prey, and then uses its powerful legs to capture and subdue its victims. The spider is also known to feed on small fish and other aquatic animals, earning it the nickname “fishing spider.” The Six Spotted Fishing Spider’s hunting behavior is unique in that it can walk on the surface of the water and even dive beneath the surface to catch prey.

Reproduction and Life Cycle
The Six Spotted Fishing Spider’s reproductive cycle typically begins in the spring, when males and females mate. The female spider will then lay a sac of eggs, which can contain up to 1,000 eggs, and attach it to a rock or vegetation. The eggs will hatch after several weeks, and the spiderlings will disperse and begin their own hunting and mating cycles. The Six Spotted Fishing Spider’s life cycle can range from several months to a year, depending on factors such as food availability and environmental conditions.
Defense Mechanisms and Predators
The Six Spotted Fishing Spider has several defense mechanisms to protect itself from predators, including its ability to release a foul-tasting liquid from its abdomen and its speed and agility. The spider is also able to dive beneath the surface of the water to escape predators. Despite these defense mechanisms, the Six Spotted Fishing Spider is still preyed upon by a variety of animals, including birds, fish, and other spiders.
The Six Spotted Fishing Spider is an important part of its ecosystem, serving as both a predator and a prey species. Its unique characteristics and behaviors make it a fascinating subject for study and observation, and its importance in maintaining the balance of its ecosystem cannot be overstated.
