Macleay's mustached bat

Macleay's mustached bat is a small bat, with an average body length of and a tail long. Fully-grown adults weigh , with males being slightly larger than females. The body is covered by greyish-brown to orange-brown fur, fading to near-white on the undersides. The head is relatively flat with a slightly upturned snout. The ears are narrow and pointed, with serrated outer edges near the tips, and a long, slightly flattened tragus. The wings have an aspect ratio of 7.6 and a wing loading of 4.6 N/m2, suitable for agile flying in cluttered environments, such as forests. The encephalisation quotient of the species has been calculated at 0.85. ==Distribution and habitat==

Macleay's mustached bats are widespread on Cuba and Jamaica, and are found wherever there are suitable caves. There are two recognised subspecies: • Pteronotus macleayii macleayii – Cuba, Isla de la Juventud • Pteronotus macleayii griseus – Jamaica ==Biology and behaviour==

Macleay's mustached bats are gregarious and nocturnal, with colonies of several thousand individuals spending the day roosting in deep and humid cave systems. They share the caves with many other local bat species, although generally clustering with members of their own species. They leave the caves shortly after sunset, and spend the night feeding on insects, primarily flies and beetles. Breeding begins in March, and results in the birth of a single young between June and July. ==References==
