Metallic Crab Spider - (Philodromus marxi)

Authored By Staff Writer | Last Updated: 1/24/2014

The sheen on the abdomen of the Metallic Crab Spider can be mesmerizing, if stops moving long enough for you to see it.





The Metallic Crab Spider is a member of the Running Crab Spider family. They are long with skinny legs and incredibly fast. This speed allows them to escape predators as well as catch dinner. Their long front legs are about the same length as the other legs, so they don't look as much like a crab as other Crab Spiders.

They can be found on tall grasses as well as the branches and leaves of trees and garden plants, or even roaming around on the ground.
