Inertia may limit efficiency of slow flapping flight, but mayflies show a strategy for reducing the power requirements of loiter
Journal Article

Inertia may limit efficiency of slow flapping flight, but mayflies show a strategy for reducing the power requirements of loiter. https://doi.org/10.1088/1748-3182/4/1/015003Predictions from aerodynamic theory often match biological observations very poorly. Many insects and several bird species habitually hover, frequently flying at low advance ratios. Taking helicopter-based aerodynamic theory, wings functioning predom...

Journal of Experimental Biology, 211(23), 3744-3749. https://doi.org/10.1242/jeb.023416The constraints to maximum walking speed and the underlying cause of the walk-run transition remains controversial. However, the motions of the body and legs can be reduced to a few mechanical principles, which, if valid, impose simple physics-based...
