The evolution and functional morphology of trap-jaw ants
… innovation in the diversification of “trap-jaw” ants: power-amplified mandibles used for prey capture, nest defense, and individual escape from predators. Insects are the most diverse and numerically abundant animal group on the planet. One feature that contributed to their evolutionary …

Comparative biomechanics and functional morphology of latch-mediated spring actuated mandibles in ants
… of animals to utilize LaMSA mechanisms are the trap-jaw ants, a polyphyletic group of ants (Hymenoptera: Formicidae) which use spring powered mandibles to rapidly capture or incapacitate prey. Trap-jaws have evolved independently more than four times across at least three subfamilies of ants, …

Evolutionary co-option of trap-jaw ant mandible strikes: defensive interactions with antlions
… evolutionary co-option at a behavioral level. Trap-jaw ants in the genus Odontomachus have a rapid and powerful mandible snap that is used during predation to disable fast or dangerous prey. Previous research suggests that some trap-jaw species may have co-opted the high forces generated by the …

The dynamics of ultrafast motion in biological and bio-inspired systems: the case study of click beetles
… hunt, or escape predators. Mantis shrimps, trap-jaw ants, fleas, and click beetles can repeatedly achieve accelerations up to 106 m/s2. These animals generate such high accelerations using complex latch and spring systems to overcome their muscle force-speed trade-offs and amplify mechanical …
