Researchers find suction-cup-shaped circular bristles give male diving beetles a mating advantage

(Phys.org) —A team of researchers working in Taiwan has found that certain types of diving beetles have a mechanical advantage over other less evolved types of diving beetles. In their paper published in Journal of the Royal Society Interface, the team describes how they compared the suction-cup type bristle gripper mechanisms used by males of one type of beetle to latch onto females, with the less evolved spatula type gripper and found the former to be a much better approach than the latter.
