title: Data from: The complex aerodynamic footprint of desert locusts revealed by large-volume tomographic particle image velocimetry

description: Particle image velocimetry has been the preferred experimental technique
 with which to study the aerodynamics of animal flight for over a decade.
 In that time, hardware has become more accessible and the software has
 progressed from the acquisition of planes through the flow field to the
 reconstruction of small volumetric measurements. Until now, it has not
 been possible to capture large volumes that incorporate the full
 wavelength of the aerodynamic track left behind during a complete wingbeat
 cycle. Here, we use a unique apparatus to acquire the first instantaneous
 wake volume of a flying animal's entire wingbeat. We confirm the
 presence of wake deformation behind desert locusts and quantify the effect
 of that deformation on estimates of aerodynamic force and the efficiency
 of lift generation. We present previously undescribed vortex wake
 phenomena, including entrainment around the wing-tip vortices of a set of
 secondary vortices borne of Kelvin–Helmholtz instability in the shear
 layer behind the flapping wings.
