Deadly Ground Crab Spider: How to Identify

Do not be alarmed by the ominous-sounding name of the Deadly ground crab spider (Xysticus funestus)! You do not have to worry about it harming you or your pets. Instead, this is an orange-colored arachnid that typically hunts for small bugs on forest grounds in North America.

Deadly Ground Crab Spider: Identification.

With its curved legs and dark orange bumps that make it look much like a crab, the potentially fatal (just joking) Deadly ground crab spider is easy to recognize. If you’re still unsure whether it’s this species, remember that its second pair of legs are substantially larger than the third and fourth sets.

In addition, members of Xysticus spiders are usually small – female adults measure up to 0.4 inches in body length, whereas male counterparts don’t exceed half that size.

Webs of Deadly ground crab spiders.

Like other crab species, deadly ground crab spiders are adept hunters rather than web spinners. They hunt in the forests and leaf litter mainly during autumn when their camouflage coloring blends perfectly with fallen orange leaves, allowing them to target small insects for prey easily.

Are Deadly ground crab spiders dangerous?

Although it has a menacing name, the deadly ground crab spider poses no threat to humans. Their minuscule fangs are too tiny and weak to puncture human skin; these spiders are extremely meek and flee upon seeing any human nearby. In uncommon incidents where they bite someone, local pain or swelling is likely the most uncomfortable experience from this creature’s nip.
