Marangoni effect is used by water striders (Veliidae) and rove beetles (Staphylinidae) to induce an ultrafast escape response against inter- or intra-specific predators. However, it is unclear if the surfactants secreted by these insects, that reduce surface tension of water, can also affect predator’s locomotion during the chasing...

Phantom crane flies (Bittacomorpha clavipes) are one of the most mysterious fliers in the insect world because it has been suggested that they are able to use their legs and body to generate aerodynamic forces and still keep a tight aerial control. Our research can be applied to micro aerial...

Helicopters seeds (Samaras) are remarkable for their aerodynamic capabilities with insects wings. We Investigate the aerodynamics and kinematics of samaras in a vertical wind tunnel. The goal of this project is to understand the unsteady mechanisms they have to fly on unsteady flow conditions...

Flying predator and their prey are commonly challenged to interact under unstable flow conditions. However, the effects produced by non-steady flows on predator-prey relationships, which demand acute aerial control and maneuvering, remain unclear. Particularly, because aerial predators are generally larger than preys, which can bias the locomotory effects...
