Ground Crab Spider – Connecticut Identification & Behavior Guide

Ground crab spiders are often found outdoors in Connecticut, especially in gardens, mulch beds, and under stones. Their crab-like sideways movement and stout bodies make them easy to recognize. Though occasionally entering homes, they are primarily outdoor predators.
