    Crab Spider - (Tmaurs spp.)

    The long front legs of Crab Spiders and occasional sideways walk demonstrates their distant relationship to more familiar marine crabs.


    Picture of Crab Spider
    Staff Writer (8/2/2017): Crab Spiders have front legs that are considerably longer than the others. Species in the Tmarus genus stretch them out in front of themselves while resting on branches and twigs. This position resembles that seen in Long-jawed Spiders. Tmarus spiders have brown mottled coloring that camouflages them. Crab Spiders are active hunters and do not spin webs to trap prey. Their ability to blend in with foliage makes it easier for them to capture unsuspecting, or oblivious, insect prey.

    BUGFINDER: What Kind of Bug is This...
    BUGFINDER allows for a quick search of the Insect Identification database by selecting primary color, secondary color, number of legs and the territory / state in question. If only one color is present on your insect, select it again as its SECONDARY color. Remember that the more details you can offer, the better your chances of finding a match. As a rule of thumb, six legs are typical for most insects whereas spiders generally have eight legs.
