 To overcome ants' powerful defences, mimics may imitate ants chemically with ant-like pheromones, visually (as in Batesian mimicry), or by imitating an ant's surface microstructure for tactile mimicry.Batesian mimics are species which typically lack strong defences of their own, and make use of their resemblance to well-defended ants to avoid being attacked by their predators, some of which may be ants.There are ant-mimicking arthropods in several different groups, described below.
