The vole is primarily a herbivore, feeding on roots, leaves, seeds, grasses, fruit, underground fungi, and nearly any type of green plant. The meadow vole is a particularly voracious eater, devouring up to 60% of its bodyweight including insects and the young of other meadow voles. Voles do not hibernate or store caches of food (except possibly the pine vole); many voles will eat bark and twigs during the winter months when green food is scarce.
