Zoid, Crazybrit.

Instead of depending on the lift an airfoil develops or the simple air-paddle like moths and dragonflies, the movement of small
insect wings create vortices which suck the insect up.

They change direction by re-aligning the wings and thus the
direction of the vortex.

Either that or they carry little jet-packs from Bees-R-Us.
