Level locomotion in wood ants: evidence for grounded running [PDF]
Journal of Experimental Biology, 2014 AbstractIn order to better understand the strategies of locomotion in small insects, we have studied continuous level locomotion of the wood ant species Formica polyctena. We determined the three-dimensional centre of mass kinematics during the gait cycle and recorded the ground reaction forces of single legs utilizing a self-developed test site.
