Telugu sex ant
Ants occupy a wide range of ecological niches and exploit many different food resources as direct or indirect herbivores, predators and scavengers.Most ant species are omnivorous generalists, but a few are specialist feeders.They were scarce in comparison to the populations of other insects, representing only about 1% of the entire insect population.Ants became dominant after adaptive radiation at the beginning of the Paleogene period.Their ecological dominance is demonstrated by their biomass: ants are estimated to contribute 15–20 % (on average and nearly 25% in the tropics) of terrestrial animal biomass, exceeding that of the vertebrates.Ants vary in colour; most ants are red or black, but a few species are green and some tropical species have a metallic lustre.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.
Ants evolved from wasp-like ancestors in the Cretaceous period, about 140 million years ago, and diversified after the rise of flowering plants.Ants evolved from a lineage within the stinging wasps, and a 2013 study suggests that they are a sister group of the Apoidea. The specimen, trapped in amber dating back to around 92 million years ago, has features found in some wasps, but not found in modern ants.During the Cretaceous period, a few species of primitive ants ranged widely on the Laurasian supercontinent (the Northern Hemisphere).Sanskrit vamrah, Latin formīca, Greek μύρμηξ mýrmēx, Old Church Slavonic mraviji, Old Irish moirb, Old Norse maurr, Dutch mier.
The family Formicidae belongs to the order Hymenoptera, which also includes sawflies, bees, and wasps. Wilson and his colleagues identified the fossil remains of an ant (Sphecomyrma) that lived in the Cretaceous period.They are the sub-order Isoptera, and together with cockroaches they form the order Blattodea.
