Daubenton's bat

Myotis daubentonii

Distribution and abundance; Legal and Conservation Status; Population Trends

The Daubenton's bat is a medium-sized bat which characteristically flies and forages just above water. It often uses its large feet to trawl for insects from the water surface. In the summer months it roosts near water using bridges and holes in trees. It mainly eats small flies, especially chironomid midges. Data on the population trends of Daubenton's bat are collected through two surveys: Hibernation Survey and Waterway Survey.
