Mole tunnels as traps
Mole tunnels are not simply passageways but traps. Earthworms, beetles, insectlarvae, in the soil may suddenly fall into a mole's tunnel where the mole harvests the food item. Incessantly active, it patrols its extensive network at least once every three or four hours and consumes vast numbers of invertebrates each day. On the rare occasions when so many worms collect in the tunnels that even a mole's appetite is sated, it gathers up the surplus, gives each of them a quick bite to immobilise them, and then stores them away in an underground larder. Some of these stores have been found with thousands of paralysed invertebrates in them.
