Ants

Ants are eusocial insects of the family Formicidae and, besides with the related families of wasps and bees, belong to the order Hymenoptera. They are a various group of more than 12,000 species, with a higher range in the tropics. They are known for their highly organized colonies and nests, which sometimes consist of millions of individuals. Individuals are divided into sub-fertile, and more commonly sterilized, females ("workers", "soldiers", and other castes), fertile males ("drones"), and fertile females ("queens"). Colonies can engage and use a wide area of land to support themselves. Ant colonies are sometimes described as superorganisms because the dependency appears to operate as a unified creature.

Ants have colonized roughly every landmass on Earth. The only places lacking indigenous ant species are Antarctica, Greenland, Iceland, parts of Polynesia, the Hawaiian Islands, and other remote or inhospitable islands. When all their entity contributions are added up, they may comprise up to 15 to 25% of the total earthly animal biomass.

Termites, sometimes called white ants, are not closely linked to ants, although they have related social structures. Velvet ants, although resembling large ants, are wingless feminine wasps.
