Arctic tundra and open meadows are ideal habitats for Lemmings, whose diet consists of grass, moss, small shrubs and insects. In the winter, they dig into the soft snow in search of food on the ground. The Norwegian Lemming is famous for its fluctuations in population every 3-4 years, when an explosive increase in numbers causes the lemmings to set out in all directions in search of food. They will cross bodies of water for this purpose, which is the origin for the myth that they commit mass suicide.
