Ants are eusocial insects of the family Formicidae /fɔrˈmɪsɨdiː/ and, along with the related wasps and bees, belong to the order Hymenoptera. Ants evolved from wasp-like ancestors in the mid-Cretaceous period between 110 and 130 million years ago and diversified after the rise of flowering plants. More than 12, 500 of an estimated total of 22, 000 species have been classified. [4][5] They are easily identified by their elbowed antennae and the distinctive node-like structure that forms their slender waists.
