Short answers, pulled from the story.
How long do ant queens live compared to other insects?
Ant queens can live for up to 30 years, and are estimated to live 100 times as long as solitary insects of a similar size. Workers survive from one to three years, while males live only a few weeks.
When did ants first evolve on Earth?
The oldest known ant fossils date to the mid-Cretaceous period, roughly 113-100 million years ago. Ants evolved from within the stinging wasps, with a specimen called Sphecomyrma found in amber dating to around 92 million years ago. Modern ant subfamilies appeared around 80-70 million years ago.
What is the total biomass of all ants on Earth?
Estimates published in 2022 put the global ant population at around 20 quadrillion individuals and their total mass at 12 megatons of dry carbon. This exceeds the combined biomass of all wild birds and mammals on Earth.
Which ant has the most painful sting in the world?
Bullet ants of the genus Paraponera, found in Central and South America, are considered to have the most painful sting of any insect and receive the highest rating on the Schmidt sting pain index. The sting of jack jumper ants can be lethal to humans, and an antivenom has been developed specifically for it.
How do trap-jaw ants use their mandibles as a weapon?
Trap-jaw ants of the genus Odontomachus can close their mandibles at peak speeds between 126 and 230 km/h, with closure happening within 130 microseconds on average. A study of Odontomachus bauri observed the ants using their jaws as a catapult to eject intruders or fling themselves backward to escape threats.
