They search for their food by climbing on the trees and shrubs. Attacker ants travel both sides creating a tube and worker ants travel between them so that they may not be attacked by anything. Drivers ants are very aggressive in nature. As Driver Ants are nomadic in nature, They make temporary colony while moving from place to place. Driver ants are smarter than most of the ant species and they plan their attack before attacking. These ants are carnivores in nature. Their bite force is so much power that their heads are used to stitch wounds.
If not run away, Driver ants can even kill a human. Driver Ant queen can grow up to 2 Inches long. Driver Ants are the biggest among all ant species.
These ants can travel 20 Meters per hour. Driver Ants have a big jaw and six powerful legs to pull things. They have dark brown and black color. Their bite hurts a lot and also its very difficult to remove their jaws from the flesh once they bite you. This is why in some parts of Africa, These ants are used to stitch the wounds. Where Do Driver Ant Live As discussed earlier, they are nomadic in nature and travel from place to place.
They create temporary colonies to keep their eggs and larva during their travel. There are found mostly in all parts of Africa.
These are also known for raiding neighbor colonies of species like termites, seeds, oil, bread and other Insect Species. Although Dead Beetles are considered as their favorite food.
Driver Ant Lifespan Driver ants live from a few weeks to several years. Army ants have a stationary phase where they create a living nest composed of their bodies, a structure called a bivouac , which protects the queen and larvae. When they move to another place, the bivouac dissolves and the workers transport the queen and larvae to greener pastures. Then, as he rode past the stretch where the ants had failed to cross the day before, he witnessed a brief but impressive scene.
Down the slope of the distant hill there came towards him a singular being, writhing rather man running, an animal-like blackened statue with shapeless head and four quivering feet that knuckled under almost ceaselessly. When the creature reached the far bank of the ditch and collapsed opposite Leiningen, he recognized it as a pampas stag, covered over and over with ants. It had strayed near the zone of the army.
As usual, they had attacked its eyes first. Blinded, it had reeled in the madness of hideous torment straight into the ranks of its persecutors, and now the beast swayed to and fro in its death agony. With a shot from his rifle Leiningen put it out of its misery. Then he pulled out his watch. After six minutes the white polished bones alone remained. Some descriptions of ant biology are exaggerated in the story for dramatic effect. The main character of the story described ants stripping a deer to bare bones in less than 10 minutes.
Ants are certainly capable of stripping a large animal-at least a hypothetical dead or immobile animal-but an animal this size would likely take days to strip and consume. Fire ants, for example, can strip a frog to bones in about 12 hours. Other descriptions, such as the wavelike movement of the ants, are more based on a need for dramatic imagery. The ants spread out and hunt in raids which could be said to resemble rivers, but nothing which would resemble a tsunami.
The story talks about the army ants eating everything in their paths, but in reality Eciton focuses mostly on insect prey. However some of their African counterparts in the genus Dorylus do attack some crops occasionally, particularly potatoes. However, the genus which is likely described in the story tends to eat bugs more than plants.
This is what a more typical encounter with army ants looks like. Eciton army ants in Panama. Picture courtesy of Smartse, via Wikimedia commons. The video above was taken in Ecuador, where Nancy and I had our own encounter with army ants. Anybody can be allergic to insect stings, and ant stings are no exception.
People who are immobile, such as infants and nursing home patients , can also be harmed by ants due to an inability to fight back. In real life ants do have some consequences for agriculture, but the relationship is a lot more complex than simply eating crops.
There are a lot of ants which are quite useful for biological control because they eat crop pests. Some cultures even divert army ants into their fields, and let them take care of pest control. Unfortunately, this is a double edged sword because ants also have very well known associations with some types of crop pests such as scales and aphids.
The ants eat the honeydew the aphids and scales produce, and protect them from predators and parasitoids. Unfortunately, they can protect them from the predators and parasitoids we use to control these pests. So they might not eat crops, but they definitely make it harder for us to control some pests. In the video below, you can watch ants drive off a ladybird beetle which was trying to eat their aphids.

Pharaoh ants, for example, are really well known pantry raiders in some areas. So Pharaoh ants can still cause medical problems, but not in the way that other ants can. Another option is to weigh them in a group, says Mike Fox from BWARS: "I would simply take a suitable container such as a specimen tube and weigh it empty, then put in a counted number of ants, say Weigh again.
Deduct the weight of the empty tube and divide it by the number of ants. Discover more about the structured social system of ants. With around 13, species worldwide, ranging in length from less than 1mm to 30mm, it's probable their weights vary greatly - though most experts seem to agree the average weight of an ant is less than 10mg.
But no-one knows how many ants there are in the world. The BBC Four documentary claims they number not 10, trillion but trillion, though it still suggests the total weight of ants equals the total weight of humans. Even by Wilson and Hoelldobler's own figures, their calculation is wrong.
