Worker ants are the most interesting members of ant colonies because they adhere to a tight hierarchy. More than 12,000 known species of ants can be found across all continents.

What is the Biggest Ant in the World?
The Dinoponera quadriceps are the biggest ant species in the world. Venomous to humans, this type of ant is native to Brazil’s warm, humid forests.
They are around 0.80 inches long and are entirely black. Dinoponera quadriceps ants are unique in that they don’t have queens but instead can reproduce regardless of gender.
They make their homes on the trunks of trees and forage for food nearby. They eat a wide variety of things, but living insects are particularly vulnerable to their venom.
Their stings can cause excruciating pain that, in some situations, can endure for up to two days.

What is the Size of the Biggest Ant in the World?
The size of the biggest ant in the world can reach a length of 3–4 cm (1.2–1.6 in), making them one of the largest ant species in the world.
The size of Dinoponera is the most striking difference between it and other genera.
Only the bullet ant, Paraponera clavata, and the bigger Pachycondyla, such as P. crassinoda, P. impressa, and P. villosa, have a worker caste comparable in size to that of the thief ant.
The finely sculptured body and deep antennal scrobes of the Paraponera clavata make it easy to recognise this species.
Pachycondyla and Dinoponera are considered to be closely related taxa.
The two lateral protruding clypeal teeth and the rows of spines on the pygidium and hypopygidium help set Dinoponera apart from Pachycondyla, in addition to their larger size.

How Does the Biggest Ant in the World Reproduce?
Some species of Dinoponera, one of the about ten ponerine genera, have lost their specialised queen caste and instead use a reproductive worker called a gamergate.
Worker hierarchies in colonies are often linear, with the lowest worker joining a group of one to five higher workers.
In the gaming community, the alpha female, or gamergate, is the top dog. The dominant female has nocturnal sex at the nest entrance with males who are not her nestmates.
After copulation, the female removes the genital capsule (a temporary sperm plug) by biting into the male’s gaster. The female becomes infertile and monogamous after mating.
Ritualised behaviours, such as antennal boxing and biting, “blocking,” and gaster stroking and curling, help the gamergate maintain control.
The Dufour’s gland secretions used by alpha females to “sting smear” rivals can cause the lower-ranking workers to immobilise the marked female.
Unfertilized eggs laid by subordinate females (beta, gamma, or delta) are typically eaten by the alpha female as a sort of “queen policing.”
Males are born at various times throughout the year in tropical species, whereas in the temperate south, the Dinoponera australis only gives birth to males between the months of May and July.
When the alpha’s reproductive capacity declines or she dies, a highly skilled worker takes over.
How Does the Biggest Ant in the World Forage?
Workers lower on the totem pole forage for food items on the substrate independently, without enlisting the help of their nestmates.
Females with greater social status are responsible for preparing and distributing small meal bits to the larvae, whereas lower-ranking females process protein resources.
Early mornings and afternoons appear to be prime time for Dinoponera gigantea foraging, while nighttime foraging is rarely observed.
Live prey, seeds, and fruits are also common components of the meals of both the Dinoponera gigantea and Dinoponera quadriceps.
Dinoponera’s taxonomic variety of prey is on par with that of other tropical ponerines, but its preferred prey size is just 2 to 3 centimetres.
The diet of this genus appears to be highly consistent throughout habitats.
What Feeds on the Biggest Ant in the World?
Over 15,700 species, subspecies, and undescribed variants of ants have been described. A new census estimates that there are around 20 quadrillion ants in the world, or about 2.5 million ants for every human.
