... deviations. During free flight, however, course changes are also signalled by other sensory systems. Therefore, it is as yet unclear to what extent motion vision contributes to course control. To address this question, we genetically rendered flies motion-blind by blocking their primary motion-sensitive...

... during free-flight manoeuvring in rose chafer beetles ( Protaetia cuprea ). We found that asymmetric flapping during aerial turns was associated with contralateral differences in chord-wise wing deformations. The highest instantaneous difference in deformation occurred during stroke reversals, resulting...

The new method is based on a projected comb-fringe technique combined with the natural landmarks on a dragonfly, allowing...

...Hanno Fischer; Eckhard Ebert ABSTRACT Tegulae are complex proprioceptors at the wing base of locusts. Deafferentation of the tegulae causes a lack of specific phasic information related to the wing downstroke and the timing of the upstroke. Employing telemetry during free flight of the locust...
