Little is known about the biology of the Sardinian long-eared bat due to the small amount of research that has been undertaken on this species, although it can be assumed that it shares a similar lifestyle to the other European long-eared bats. Long-eared bats (Plecotus species) are typically gregarious creatures that roost in colonies, and mate in the autumn, hibernate in winter, and give birth in spring. Long-eared bats generally give birth to a single young, which is weaned after six to seven weeks and reaches sexual maturity after one to three years (3).
The large ears and eyes suggest that the Sardinian long-eared bat uses a combination of echolocation, sight and sound to locate and catch prey such as moths and other flying insects, in the same way as other long-eared bats. The brown long-eared bat (Plecotus auritus) has been observed gleaning insects by listening to tiny movements made by the prey; this could also be a potential strategy used by the Sardinian long-eared bat (5).
