The true Crab spiders are a group of spiders constituting the family Thomisidae or thomisids. Thomisids are non-web-building ambush predators whose coloration often matches the substrates they are found upon. They are called crab spiders because of their first two pairs of legs, which are held out to the side giving them (with their flattened, angular bodies) a crab-like appearance. These are termed laterigrade legs. Also, like crabs, these spiders move sideways and backwards more easily than forwards. Suborders Araneomorphae Mesothelae Mygalomorphae See the taxonomy section for families Spiders are invertebrate animals that produce silk, have eight legs and no wings. ...

Crab spiders often live on flowers.
True crab spiders differ from philodromid crab spiders in usually having numerous hair-like setae on their bodies and in having the first pair of legs the longest. Philodromid crab spiders have scale-like setae and the second pair of legs is usually the longest. True crab spiders include the flower spiders in the genera Misumena, Misumenops, and Misumenoides in North America, as well as the nominate Thomisius in the Old World. These spiders may change their coloration between white and yellow to match the color of the flower they are hunting from. The Thomisus which hunts in heather in Britain is a well-matched shade of pink. It may be that these flower spiders even hunt in flowers which match their ultraviolet reflectance. The brownish, bark and ground-dwelling genus Xysticus is widespread in distribution, with many species in North America. Members of the strange genus Tmarus may look much like a small knot on a branch. Other odd thomisids include those that live in carnivorous pitcher plants and those that appear to mimic orchid flowers.
