    Red Ant-Mimic Spider - (Castianeira sp.)

    Red Ant-Mimic Spiders are clever little arachnids. Their disguise gives them access to more than just safety from potential predators.

    Staff Writer (1/28/2014): Red Ant-Mimic Spiders play both sides of the game: defense and offense. Their ability to be confused as red ants helps keep their predators at bay. It also allows them to get very close to their unsuspecting red ant prey.

    Red Ants are usually found in or near their colonies. When one is injured, others will come and their bites are annoying, if not painful, to a predator. Red Ant-Mimic Spiders can take advantage of the wide berth they are given by other invertebrates. They can also get close enough to kill and eat an ant without drawing alarm because it blends in well with the species. Other insect prey that are indifferent to the presence of ants will not see an attack coming until it is too late.
