Those studies will be especially important for a fleet of robotic insects in development, including robobees created by a team at Harvard University. But now, Dickinson says, researchers are more interested in the finer points of how insects control themselves once they're in the air. Other studies have confirmed that bees can flyin one of the more colorful projects, in 2001, a Chinese research team led by Lijang Zeng of Tsinghua University glued small pieces of glass to bees and then tracked reflected light as they flew around in a laser array.
The eyes of those mini-hurricanes have lower pressure than the surrounding air, so, keeping those eddies of air above its wings helps the bee stay aloft.
The wing sweeping is a bit like a partial spin of a "somewhat crappy" helicopter propeller, Dickinson said, but the angle to the wing also creates vortices in the airlike small hurricanes. In fact, pollinators are responsible for 1 out of every 3 bites of food you take. This is important for plant reproduction and food production. An airplane's wing forces air down, which in turn pushes the wing (and the plane it's attached to) upward. Bees are beneficial insects that pollinate flowering plants by transferring pollen from one flower to another. Large bees usually have a length of 20mm or more.
Medium bees are usually 15-20mm in length. Small bees are usually 10-15mm in length. Tiny bees are usually less than 10 mm in length. The fluid dynamics behind bumblebees' flight are different from those that allow a plane to fly. Bees range from tiny insects with a body length of under a centimeter to large, armored juggernauts of two or three centimeters in length.
