How far can fleas jump compared with their body length?

Fleas are remarkable for their jumping ability, which is facilitated by highly developed legs and a specialized protein called resilin. By utilizing a muscle-controlled catch mechanism that stores and releases energy, these insects can leap horizontal or vertical distances up to 200 times their body length. This impressive feat, which also involves an acceleration of 200 gravities, has led to the description of fleas as insects that "fly" with their legs.1
