Ants are social insects of the family Formicidae and, along with the related wasps and bees, belong to the order Hymenoptera. They are easily identified by their elbowed antennae and a distinctive node-like structure that forms a slender waist. Ants form colonies that range in size from a few dozen predatory individuals living in small natural cavities to highly organised colonies that may occupy large territories and consist mostly of sterile wingless females forming castes of “ workers”. “soldiers”, or other specialised groups.
