Airflow elicits a spider's jump towards airborne prey. I. Airflow around a flying blowfly.
The hunting spider Cupiennius salei uses airflow generated by flying insects for the guidance of its prey-capture jump. We investigated the velocity field of the airflow generated by a freely flying blowfly close to the flow sensors on the spider's legs. It shows three characteristic phases (I-III). (I) When approaching, the blowfly induces an airflow signal near the spider with only little flu...
متن کاملAirflow elicits a spider's jump towards airborne prey. II. Flow characteristics guiding behaviour.
When hungry, the wandering spider Cupiennius salei is frequently seen to catch flying insect prey. The success of its remarkable prey-capture jump from its sitting plant into the air obviously depends on proper timing and sensory guidance. In this study, it is shown that particular features of the airflow generated by the insect suffice to guide the spider. Vision and the reception of substrate...
متن کاملAugmenting Simulations of Airflow around Buildings
Computational fluid-dynamics (CFD) simulations have become an important tool for the 10 assessment of airflow in urban areas. However, large discrepancies may appear when simulated 11 predictions are compared with field measurements because of the complexity of airflow behaviour 12 around buildings and difficulties in defining correct sets of parameter values, including those for inlet 13 condi...
متن کاملInduced airflow in flying insects I. A theoretical model of the induced flow.
A strong induced flow structure envelops the body of insects and birds during flight. This flow influences many physiological processes including delivery of odor and mechanical stimuli to the sensory organs, as well as mass flow processes including heat loss and gas exchange in flying animals. With recent advances in near-field aerodynamics of insect and bird flight, it is now possible to dete...
متن کاملInduced airflow in flying insects I . A theoretical model of the induced flow Sanjay
Introduction Flapping birds and insects are often likened to revolving propeller blades or rotors because their wings generate lift by steadily pushing air downward. Two influential aerodynamic models of flight in insects (Ellington, 1984c) and birds (Rayner, 1979) drew much inspiration from the extensive theoretical work on rotor aerodynamics. These models focused primarily on the far-field wa...
