    Bark Crab Spider - (Bassaniana versicolor)

    The long and thick front pairs of legs on the Bark Crab Spider help explain part of this arachnid's name.




    Staff Writer (6/25/2015): Bark Crab Spiders are usually found in woods, forests and parks on tree bark, short plants, the forest floor or under stones and deadwood. They are active hunters and do not spin webs for ensnaring prey. Spider silk for this species is used during mating.

    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. 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.
