The Noctule is our largest bat. All British bats are nocturnal, feeding on midges, moths and other flying insects which they find in the dark by using echolocation. Noctules roost in holes in trees and can be seen feeding on insects over the tree canopy; they particularly enjoy feeding on flying beetles such as the large Cockchafer. Noctules hibernate over the winter, between November and April.
Noctules and other bats are declining as roost sites are lost to development and pesticide-use reduces their insect-prey. But you can help our bats in your own garden; why not try putting up a bat box? Pick a tree that gets some sun during the day, but is near to a hedge or other trees. All UK bats and their roosts are protected by law, which means it is illegal to harm or disturb them.
