Ants are great insects, and scientists have recently discovered that they have another skill, which is to fly. This achievement was published in the latest issue of Nature. The accidental discovery was made when Steven Yanovac of the University of Texas Medical School collected mosquito specimens from the rainforests of northeastern Peru. "When I was working, I was covered in ants and I just kept knocking them out. I happened to notice that they didn't fall directly on the ground, but they had a twist in the air and they could return to the trunk. Do they fly?†Janowak painted a paint on the ants to track their whereabouts, and asked his colleagues to shoot their fall trajectory with a high-speed camera. It was found that the ant's drop curve was "J" shaped and was divided into three stages: first, a free fall of 2 to 3 meters. At this time, they spread their legs in all directions in hopes of increasing air resistance and slowing the rate of decline. Then it turns in the air and begins to climb; finally it flies back to the trunk. Yanovac noted that this kind of flight is actually a type of gliding. The study found that the success rate of these ants “flying†back to the trunk was as high as 85%, and they averaged 4.3 m/s when they landed. The ants were also the first animals the scientists discovered to fly backwards, heading backwards when they glided. According to Janovyak, this may be due to the fact that its hind legs are longer than the front legs and it is easier to grasp the trunk quickly. Yanovak pointed out that this kind of "light work" is their "unreserved child". The ants live in the trees. Molds and scavengers in the lower layers of trees are their natural enemies. With gliding skills, ants can safely return to the trunk, whether it is blown by the wind, hit by other animals, or jumped off in order to avoid danger.
