These bats eat winged ants, moths, and other insects, but are particulary fond of beetles. Abstract. A single noctule roosts in buildings are only gathering roosts, the colonies moving off at the end of May and early June. Data on the breeding origin of hibernating noctule bats also suggest that artificial roosts may not only be important for local but also for distant populations. One or two pups are born between May and June. Head to the woods just before dark for the best chance of seeing this species. Registered in England No. Maternity colonies are not formed until the following spring when both males and females begin to nest in tree holes, crevices in buildings and nest boxes. Sexual segregation during the breeding season is common in many temperate bat species, and may be related to sex-specific thermoregulatory, microclimatic, or energetic requirements. Noctules roost in holes in trees and bat boxes, but rarely in buildings. Images © protected Woodland Trust. It is also protected by law in the UK under the Wildlife and Countryside Act 1981.
