Wasserfledermaus
It is one of a very small number of sites in Britain at which the Red Data Book hoverfly "Chalcosyrphus eunotus" has been found. A wide range of butterflies occurs here, including silver-washed fritillary and white admiral. A number of bat species have also been recorded at the site including the common pipistrelle ("Pipistrellus pipistrellus"), soprano pipistrelle ("Pipistrellus pygmaeus"), noctule ("Nyctalus noctula"), Daubenton's bat ("Myotis daubentonii") and lesser horseshoe bat ("Rhinolophus hipposideros").
