About

Sometimes referred to as the 'Water Bat', the Daubenton's Bat forages for small flies, such as midges, caddisflies and mayflies, just above water; it can even use its feet and tail to scoop up insects from the water's surface as it forages. Daubenton's Bats roost near water, under bridges or in tunnels, and in holes in trees. During the summer, females form maternity colonies to have their pups. Daubenton's Bats hibernate underground over winter, in caves, tunnels and mines.
