A flea can jump 60 times its length in height and 110 times its length in distance, equivalent to a 1.8 m (6 ft) adult human jumping 110 m (361 ft) vertically and 200 m (656 ft) horizontally. Rarely do fleas jump from dog to dog.

So Sutton and Burrows have finally settled the argument and resolved how fleas jump. The insects transmit the force from the spring in the thorax through leg segments acting as levers to push down on the tarsus (toe) and launch the 0.7mg animals at speeds as high as 1.9m/s.

19 de nov. de 2019 · Fleas are remarkable jumpers: They can travel 200 times their own body length in a single leap, and can withstand acceleration forces of 100 Gs. But exactly how do they make such incredible jumps?
Fleas are able not only to move through dense host pelage, but also to jump, to move through the substrate of a host’s burrow or nest and to move on vertical surfaces. The diversity of modes of flea locomotion and their efficiency using these modes for host location and exploitation suggest that these locomotory
