2. Figure 1 Moth wings and bat wings both make leading edge vortices.
(A) The wings of a large hawk moth create a prominent leading edge vortex during the downstroke, as visualized on a tethered animal flying in a smoke rake within a wind tunnel. The photograph shows the flow around a thin section of the wing (modified from [19] with permission of the Company of Biologists). (B) Bat wings, operating at the same Reynolds number (Re ∼ 5000), also create a leading edge vortex, as visualized using the technique of digital particle image velocimetry (modified with permission from [4], with permission from AAAS).
