Galloping dung beetles
Pachysoma dung beetles in Africa have a gait never before described in insects — almost a gallop. Biologists hadn’t recognized the motion because it’s hard to see scuttling beetle legs, said Jochen Smolka of Sweden’s Lund University. He videotaped beetle sprints and analyzed them in slow replays. Most insects move their six legs as two tripods.
