    Running Crab Spider - (Philodromus spp.)

    The Running Crab Spider is always on the hunt for food. Its remarkable speed make it a stealthy predator while simultaneously making it hard to catch.




    Staff Writer (1/30/2014): These fast-moving spiders are agile enough to outrun predators as well as human hands trying to collect them. Their camouflage coloration makes it difficult to spot them in nature when they aren't moving.

    Running Crab Spiders have a front pair of legs that look longer than the back legs, but they really aren't. They are close relatives to members of the Crab spider family so it may be easy to mistake them. The way they hold and use their front legs is similar to true Crab Spiders.

    Running Crab Spiders do not spin silk webs to catch insects. They chase them down, bite them to inject their venom and consume them when they like.
