Bees can adjust flight speed

Picture 1 of Bees can adjust flight speed Doctoral student Emily Baird and colleagues at Australia's National University found honey bees have an effective way to maintain flight direction in the air and do not collide with obstacles.

They can adjust their flight speed to keep things flying through them at constant frequency. So they can adjust the speed and avoid colliding with other objects without knowing where they are flying and how far from the ground.

Scientists know that honeybees rely heavily on visual information to direct flight, but Baird's team wants to determine whether bees also use vision to control flight speed, or depending on some senses. another to speed up. They sent many bees through a rectangular straight tunnel then moved the two sides of the tunnel to create patterns in the same direction or against the bee's flight direction. Test results show that bees automatically adjust flight speed to keep their surroundings unchanged.

' All they do is observe the speed at which the underground and surrounding environments are moving through them and so on. So in an open environment like in a field, bees will fly high and fast, but when entering a noisy environment, they will automatically decelerate to avoid hitting obstacles ', according to Baird.
