Jumping mechanism in the marsh beetles (Coleoptera: Scirtidae).

ABSTRACT: The jumping mechanism with supporting morphology and kinematics is described in the marsh beetle Scirtes hemisphaericus (Coleoptera: Scirtidae). In marsh beetles, the jump is performed by the hind legs by the rapid extension of the hind tibia. The kinematic parameters of the jump are: 139-1536 m s^-2 (acceleration), 0.4-1.9 m s^-1 (velocity), 2.7-8.4 ms (time to take-off), 0.2-5.4 × 10^-6 J (kinetic energy) and 14-156 (g-force). The power output of a jumping leg during the jumping movement is 3.5 × 10³ to 9.6 × 10³ W kg^-1. A resilin-bearing elastic extensor ligament is considered to be the structure that accumulates the elastic strain energy. The functional model of the jumping involving an active latching mechanism is proposed
