Ant-mimic Spiders make quick darting movements that make them look like ants. Looking like an ant keeps them from being eaten by real ants. They are called “ant mimics” because they have a “false” waist and they move like ants.Their color is mostly reddish-brown, but they can also be orange, brown, or black. There are often light or dark bands or spots on the body. Adult females are slightly larger than males.These spiders resembles themselves with the ants (predators) to confuse them & use them as food.
