The mouse-eared bats or myotises are a diverse and widespread genus (Myotis) of bats within the family Vespertilionidae. The noun " myotis " itself is a Neo-Latin construction, from the Greek " muós (meaning "mouse") and " oûs " (meaning ear), literally translating to "mouse-eared".
The 121 extant species of Myotinae are divided between three genera: Eudiscopus and Submyotodon with one species each, and Myotis, or the mouse-eared bats, with the other 119. A few extinct prehistoric myotine species have been discovered, though due to ongoing research and discoveries the exact number and categorization is not fixed.
It owes its name to the genus Vespertilio, which takes its name from a word for bat, vespertilio, derived from the Latin term vesper meaning 'evening'; they are termed "evening bats" and were once referred to as "evening birds". (The term "evening bat" also often refers more specifically to one of the species, Nycticeius humeralis.)
The Greater mouse-eared bat is relatively large for a member of the genus Myotis, weighing up to 45 grams (1.6 oz) and measuring 8 to 9 cm from head to tail (a little larger than a house mouse, Mus musculus), making it one of the largest European bats. [3] It has a 40 cm wingspan, with a forearm length of 6 cm, and a 4 to 5 cm long tail.
For instance, the Mexican free-tailed bat fly for more than one thousand miles to the 100-foot (30 m) wide cave known as Bracken Cave every March to October which plays home to an astonishing twenty million of the species, [216] whereas a mouse-eared bat lives an almost completely solitary life.

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. [ 3 ]
