Velocity vector files from PIV measurements of the wake behind a flying beetle

These are the velocity vector files from the PIV measurements in the wake of Batocera rufomaculata flying tethered in a wind tunnel. The data correspond to the manuscript: 

The aerodynamics and power requirements of forward flapping flight in the mango stem borer beetle (Batocera rufomaculata), by Urca et al. published by the journal Integrative Organismal Biology. 

The abstract of the coresponding paper is: 

The need for long dispersal flights can drive selection for behavioral, physiological and biomechanical mechanisms to reduce the energy spent flying. However, some energy loss during the transfer of momentum from the wing to the fluid is inevitable, and inherent to the fluid-wing interaction. Here, we analyzed these losses during the forward flight of the mango stem borer (Batocera rufomaculata). This relatively large beetle can disperse substantial distances in search of new host trees, and laboratory experiments have demonstrated continuous tethered flights that can last...
