What do Daubenton's bats eat?

Flies, midges and caddisflies are the species’ main prey. They hunt these insects by flying low over water and catching them in their mouths or scooping them up with their tails. Prey is often eaten on the wing, but may be taken to a perch if particularly large.

How do Daubenton's bats breed?

Mating takes place in autumn, with the young born the following spring or summer. Females gather to raise their young in maternity roosts, with the pups becoming fully independent after around two months.


Daubenton’s bats tend to hibernate alone, choosing warm sheltered spots underground, such as in mines or caves. The species become less active from October onwards as the weather begins to cool. By December, bats are in full hibernation and will not emerge until the onset of spring.
