The Leisler’s bat is similar to the noctule, but smaller, with longer fur – particularly around the shoulders and upper back. This gives it a lion’s mane appearance. Formerly known as the hairy-armed bat, Leisler’s are naturally a forest species, while also found in suburban areas where they may be attracted to insects around street lights.
