The long and thick front pairs of legs on the Bark Crab Spider help explain part of this arachnid's name.
When moving, Bark Crab Spiders resemble a crab by walking sideways or backwards as well as forward. The long front pairs of legs are helpful in restraining insect prey while it is bitten. The black spider is covered in light brown or ivory speckles. The speckling patterns vary between species. It may allow the spider to more closely resemble bird droppings or variations in tree bark coloring, making it easier to catch unsuspecting insects. The abdomen is wide and flat.
Bark Crab Spiders do not bark. They silently roam the exterior of trees, searching for insects to eat. Bark Crab Spiders are usually found in woods, forests and parks on tree bark, though they also include short plants, the forest floor, and areas under stones and dead wood as part of their hunting ground. They are active hunters and do not spin webs for ensnaring prey. Spider silk for this species may be mostly reserved for courting, where males adorn prospective females with strands of silk.
