Facts, Identification & Control
Among arthropods, jumping spiders, or salticids, are known for their superior eyesight. Jumping spiders are equipped with eight eyes, four of which are apportioned to the face and four of which are located at the highest point of the carapace. Long and tubelike, the two eyes located at the center of the face have limited perspective and high resolution. In contrast, the other eyes have low acuity and a wider field of view.
Behavior, Diet & Habits
Jumping spiders belong to the Family Salticidae. With over 4,000 species known throughout the globe, tropical regions are most influenced. However, some species thrive in the frigid Himalayas. Over 300 species exist within North America. Jumping spiders tend to exhibit dull coloration, although the bodies of some males may glisten.
Jumping spiders are known for their swift reflexes and leaping abilities. These spiders are capable of leaping as high as 25 times their own size and, as such, are extremely capable predators. Jumping spiders also possess impressive eyesight.
Although jumping spiders are not web-weaving arachnids, they do produce silk. Their silk is used to mark retreats and to protect eggs. Silk may also function as a dragline while jumping, allowing jumping spiders to control their fall and trace their steps.
Signs of Jumping Spider Infestation
Jumping spiders are unlikely to infest indoors. They would likely be observed outdoors in vegetation.
Jumping spiders are also famous for their agility. Jumping spiders are some of the fastest-moving arthropods in existence and, as their name suggests, are capable of leaping. The circulatory system of these spiders is responsible for their mobility. When blood pressure rises in their limbs, their bodies move by way of released pressure.
