During one period of four hours, beginning just 35 minutes after we had laid out a newly dead mouse on birchleaf litter, nine burying beetles arrived. Each beetle followed the guidance of the olfactory organs in its antennae. It dropped to the ground within three meters of the mouse, quickly folded its flying wings under its wing covers and came crashing through the litter to the carcass. There, after only a moment's hesitation, the beetle turned over onto its back, slid under the body and lifted the mouse slightly from the ground, apparently to test whether the body was movable.
