    Macrotus is a genus of bats in the Neotropical family Phyllostomidae. This genus contains two species, Macrotus californicus commonly known as California Leaf-nosed Bat and Macrotus waterhousii commonly known as Mexican or Waterhouse's Leaf-nosed Bat. The range of this family includes the warmer parts of the southwestern United States, Mexico, Central and South America, and the Bahama Islands. Characteristic for the genus are large ears and the name giving triangular skin flap above the nose, the "leaf". The California Leaf-nosed Bat inhabits the arid deserts of the southwestern United States as far north as Nevada, south to Baja California and Sonora, Mexico. The California Leaf-nosed Bat is of medium size, with a total length between 9 and 11 cm Its most distinctive features are the large ears, connected across the forehead. The body is pale grayish brown dorsally with whitish under parts. The pelage (fur) on the body is silky, the hairs on the back about 8 mm, on the front about 6 mm long. The posterior base of the ears are covered with hair of a woolly texture while the interior surface and most of the anterior border shows scattered long hairs. The flight membranes are thin and delicate; the wings are broad and the tail is slightly shorter that the long hind limbs and extends several millimeters beyond the uropatagium (see Bat). Macrotus waterhousii is also a big eared Bat which has ranges from Sonora to Hidalgo Mexico, south to Guatemala and the Greater Antilles (excluding Puerto Rico) and Bahamas. This species roosts primarily in caves, but also in mines and buildings. This species is also insectivorous (see insectivore), primarily consuming insects of the order Lepidoptera and Orthoptera. The mating and parturition times of M. waterhousii vary from island to island with 4–5 months gestation.
