Ants (family Formicidae in the order Hymenoptera) are the most species-rich of all social insects, with more than 12,000 described species and many others awaiting description. [1] Formicidae is divided into 21 subfamilies , of which 17 are extant and four subfamilies are extinct , described from fossils .
Ants have colonised almost every landmass on Earth. Their population is estimated as between 10 16 –10 17 (10-100 quadrillion). [29] With an estimated 20 quadrillion ants their biomass comes to 12 megatons of dry carbon, which is more than all wild birds and non-human mammals combined. [30] [31] [32]
Ants have colonised almost every landmass on Earth. The only places lacking indigenous ants are Antarctica and a few remote or inhospitable islands. Ants thrive in moist tropical ecosystems and may exceed the combined biomass of wild birds and mammals. Their success in so many environments has been attributed to their social organisation and ...
Beginning in the 1990s, molecular (DNA sequence) data have come to play a central role in attempts to reconstruct the ant "tree of life".Molecular phylogenetic analyses based on multiple nuclear genes have yielded robust results that reinforce some preexisting views but overturn others – and suggest that there has been considerable morphological convergence among some ant lineages.
The colony was estimated to contain 306 million worker ants and one million queen ants living in 45,000 nests interconnected by underground passages over an area of 2.7 km 2 (670 acres). [14] In 2000, an enormous supercolony of Argentine ants was found in Southern Europe (report published in 2002). [ 15 ]
Hu’s research team found in similar experiments, published in Biology Open in February 2022, that rafting ants consumed almost 43 percent more energy than ants on dry land. But the larger the ...
Most ant species will send individual scouts to find food sources and later recruit others from the colony to help; however, army ants dispatch a cooperative, leaderless group of foragers to detect and overwhelm the prey at once. [3] [5] Army ants do not have a permanent nest but instead form many bivouacs as they travel.
Carpenter ants (Camponotus spp.) are large ants (workers 7 to 13 mm or 1 ⁄ 4 to 1 ⁄ 2 in) indigenous to many forested parts of the world. [ 4 ] They build nests inside wood, consisting of galleries chewed out with their mandibles or jaws, preferably in dead, damp wood.
