Codes and Macros1. The effect of air resistance on the jump performance of a small parasitoid wasp, Anagyrus pseudococci (Encyrtidae). When using these files please cite Urca and Ribak (2018) Journal of Experimental Biology (In press) MATLAB code to simulate jumps in A. pseudococci
Analysed jump data - A. Pseudococci
Image and Video PIV study of forward flight aerodynamics in the mango stem borer (B. rufomaculata). The image shows the vortices shed behind one of the beetles as it flies tethered in our wind tunnel. The study was carried out in collaboration with Prof. Roi Gurka of Coastal Carolina University. See our paper in Integrative Organismal Biology

Ever wondered what it's like to be the size of a miniature insect? For one thing, electrostatic forces can overcome your weight and become a serious problem. The video shows an ant in a 155 kV/m electrostatic field. The set-up was built to measure the ability of tiny whiteflies to accumulate and store an electrostatic charge. You can read about the effect of ES fields on miniature flying insects in our J Comp Phys A paper

Slow motion movie of a whitefly taking-off in a powerful jump while the wings in the resting position stabilize body orientation.
To read about take-off stabilization in whiteflies see our paper in the Journal of Experimental Biology Slow motion movie of a pair of blue-tailed damselflies flying in the 'wheel (copulation) position'
See our paper in Sci Nat to read how the two sexes contribute to this unique form of linked flight Flight-mill measurements of long-distance flight endurance in the Mango stem borer (Batocera rufomaculata)
See our paper in the Journal of Insect Physiology to read how conditions during larval development affect the ability of the adults to fly long-distance The Red Palm Weevil flying in a flight-mill and making banked turns during free-flight. See our paper in Plos One to read how flight-mills affect the flight of the insect tested
The wings of Rose-chafers ellastically deform during flight. See our paper in the Royal Soceity Open Science to read on how flexural stiffnes scales with body mass in these beetles to keep wing twist and camber contant
Slow motion movie showing the powerful take-off jumps of tiny parasitoid wasps. To read on this unique take-off and how it is affected by air-resistance See our paper in J Exp Biol.
How much extra weight can a male damselfly carry in flight (hint an extra ~150% of its body weight)? To read how we measured it and how it relates to copulatory flight see our recent paper in J Insect Physiol
