The members of the genus OTopTERUS are among the large species 
of the moderate sized bats, and are conspicuous for their huge ears. 
They are not over-particular as to their diet, and eat insects, fruits, 
and small bats when they can get them. They can rise into the air 
from a horizontal surface, a feat quite impossible to many species 
of other genera, and if they take up their abode in a house, it is said 
they always select the cellar, never the roof.
