A whirligig beetle darts rapidly here and there setting off ripples that are reflected when they reach the edge of the pond or collide with another object or insect on the surface of the water. Researchers have found out that the ripples sent out by each whirligig beetle in a pond are unique and can be identified and monitored by the sender. This way they can distinguish food from other whirligig beetles.
