Prior research has shown that they use wing flapping to blow away pests ... In this new effort, the researchers found yet another way the bees repel small would-be invaders, such as ants ...

The wingspan of a plane is large enough to satisfy the lift equations for flight, so they don't need to flap. But the small wings of a bee compared to its relatively fat body are not. A regular ...

which stated the bumble bee should not be able to fly under normal rules of aerodynamics, until now science was been unable to explain how mosquitoes managed to flap their wings through such a ...

A bee, with only two wings ... generating the mechanical force needed for wing flapping. Previous designs struggled with buckling at high frequencies, reducing power and efficiency.
