Concept
Microbat
Summary
Microbats constitute the suborder Microchiroptera within the order Chiroptera (bats). Bats have long been differentiated into Megachiroptera (megabats) and Microchiroptera, based on their size, the use of echolocation by the Microchiroptera and other features; molecular evidence suggests a somewhat different subdivision, as the microbats have been shown to be a paraphyletic group.
Microbats are long. Most microbats feed on insects, but some of the larger species hunt birds, lizards, frogs, smaller bats or even fish. Only three species of microbat feed on the blood of large mammals or birds ("vampire bats"); these bats live in South and Central America.
Although most "Leaf-nose" microbats are fruit and nectar-eating, the name “leaf-nosed” isn't a designation meant to indicate the preferred diet among said variety. Three species follow the bloom of columnar cacti in northwest Mexico and the Southwest United States northward in the northern spring and then the blooming agaves southward in the northern fall (autumn). Other leaf-nosed bats, such as Vampyrum spectrum of South America, hunt a variety of prey such as lizards and birds. The horseshoe bats of Europe, as well as California leaf-nosed bats, have a very intricate leaf-nose for echolocation, and feed primarily on insects.
Microbats use echolocation, whereas megabats do not typically. (The Egyptian fruit bat Rousettus egyptiacus is an exception, but does not use the larynx echolocation method of microbats, instead giving scientists the theory that it clicks using its nasal passages and back of its tongue.)
Microbats lack the claw at the second finger of the forelimb. This finger appears thinner and almost bonded by tissue with the third finger for extra support during flight.
Megabats lack tails, with the exception of a few genera such as Nyctimene, whereas this trait only occurs in certain species of microbats.
The ears of microbats possess a tragus (thought to be crucial in echolocation) and are relatively larger than megabat ears, whereas megabat ears are comparatively small and lack a tragus.
