Phase-averaged vortex wake of a desert locust (L6). Iso-surfaces of Q = 0.007 are coloured by vorticity in the spanwise axis (ωy: (a,c)) and vertical axis (ωz: (b,d)). Different structures are more distinct when resolving vorticity in alternative axes, reflecting the varying representations of the wake if using conventional 2D-3C PIV illumination planes. (a,b) side views; (c,d) rear views.
