I need to tell you something very important about bees

I simply need to inform you of this crucial fact about bees: when bees get trapped in water, they use their wings as hydrofoils to return to land safety.

Although bees can float, they cannot fly with wet wings and, worse yet, are not strong enough to free their wings from water. surface. This may seem like a death sentence if you accidentally fall into a pool or puddle. But never fear. They found that out.

Researchers Chris Roha and Morteza Gharib at Caltech Graduate Aerospace Laboratories collected bees from a garden in Pasadena, California, placed them in plastic tubes, and lightly tapped the tubes until the bees dropped about an inch or two of water.. The pair then filmed the bees with high-speed cameras, observing the strength and frequency of their wings.and how fast they moved. They also shone lights above the bees to see the shadow patterns. produced by the waves.

The bees cast across the water, flapping with slower, shallower wingseat what they do Use to fly. ºThe agitation created asymmetric wave patterns that differed in front and in front of the bee, demonstrating that the bees were actually using their wings to lift waves that would push them forward. Bees traveled at rates of up to three bee lengths per second. You go, bee!

However, it is clear that water is not the favorite habitat of bees. "Compared to the locomotion of the water surface of other insects, neither the speed nor efficiency achieved by bee hydrodynamics impress," write the authors in the article published in the Proceedings of the National Academy of Sciences. But the hydrofoil technique seems to be unique among insects that can move in water, according to the newspaper.

Tflapping its wings was enough for the bees of a local pond to move away from the water. They I traveled several meters to reach land to dry before returning regular bee business.

There are limitations to this. works; they just modeled the more general characteristics of wing movement and did not include wing befound. The model also does not explain gravity or surface tension in water.

As to why a couple of engineers in aaerospace laboratory were studying bees, well, The authors write that the mechanism can inspire hybrid air-water vehicles, in which the crash offers air and water propulsion without drastic changes in vehicle shape. The team modeled the bee wings in action and maybe their work could be used someday to really create this vehicle.
