Oscillations of force in the standing legs of a walking insect (Carausius morosus)

In the experiments presented here adult stick insects (Carausius morosus) walk on a treadwheel with various legs standing on platforms fixed relative to the body of the insect. These standing legs produce large forees directed towards the rear which are modulated in the rhythm of the walking legs. Neighbouring legs which both stand on a platform often oscillate “in phase”. Possible reasons for the occurrence of the force oscillations are discussed.
