Driver ant queens are the largest ants on Earth and have the greatest egg-laying capacity among insects, laying several million eggs each month. [11] Several species in this genus carry out raids on termitaria, paralyzing or killing termites and carting them back to the nest. [12] Colonies of driver-ant species have only one queen. [13]
Males or drones of all dorylus species are so called "sausage flies" and are among the largest ant morphs. Some Dorylus molestus queen are the largest known extant ants. . Queens typically grow to 5.2 centimetres (2.0 in) but can reach 8 centimetres (3.1
Dorylus laevigatus is a member of the army ant genus Dorylus, or Old World army ants. More specifically known as "driver ants", the genus Dorylus is abundant throughout Africa and stretches into tropical Asia , where D. laevigatus is primarily found.
Due to the queen's large reproductive potential, a colony of army ants can be descended from a single queen. [10] When the queen ant dies, there is no replacement and army ants cannot rear emergency queens. Most of the time, if the queen dies, the colony will likely die too. Queen loss can occur due to accidents during emigrations, predator ...
The largest of ants, and the heaviest species of the family, are the queens of Dorylus helvolus, reaching a length of 5 cm (2.0 in). The ant that averages the largest for the mean size of the whole colony is Dinoponera gigantea, averaging up to 3.3 cm (1 + 1 ⁄ 4 in).
Carebara species have permanent nests, while real army ants have only temporary nests (Dorylus) or form a bivouac with their own bodies (Eciton). Colonies of real army ants have only one queen, so when she dies, the workers may try to join another colony, or the rest of the colony also dies; Carebara colonies can have many (up to 16) queens.
T. gigantea is the largest giant ant ever found, larger than the biggest extant giant ants, which are the five-centimetre-long (2.0 in) driver ants of the genus Dorylus, found in Central and East Africa. [1] [6] The fossils indicate that the males grew up to 3 centimetres (1.2 in) and the queens grew to 7 centimetres (2.8 in). It had a wingspan ...
The subfamily Formiciinae represents one extinct genus of ants dating back to the Eocene. [b] Ants of the genus Titanomyrma are the largest ants ever known, with queen specimens the size of small hummingbirds. Fossils have been collected from the state of Wyoming and in Germany. [106] [107]
