There are tons of ants, and thousands of species, with more than 12,500 of an estimated total of 22,000 species classified, and there are so many ants that it is estimated that they may form 15–25% of the entire terrestrial animal biomass!
This one above is shadowed against a leaf, as it tends to its aphids.
They are easily identified by their elbowed antennae and the distinctive node-like structure that forms their slender waists.
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 of millions of individuals. Larger colonies consist of various castes of sterile, wingless females, most of which are workers (ergates), as well as soldiers (dinergates) and other specialised groups.
Ant societies - unlike my own family - have division of labour, communication between individuals, and an ability to solve complex problems.
