Xysticus gulosus

Also known as Ground Crab Spider

Ground crab spiders lurk cryptically among tree bark, leaf litter, and low vegetation, matching their mottled brown bodies to decaying forest debris across North America. Rather than weaving capture webs, they rely on patience and powerful, laterally projecting front legs to seize passing insects several times their own size. During courtship in late summer, males anchor females loosely with silk strands before mating, after which females guard flat, disc-shaped egg sacs hidden under bark or stones.
