It was first described as a species in 1796. Compared to other microbats, the big brown bat is relatively large, weighing 15–26 g (0.53–0.92 oz) and possessing a wingspan of 32.5–35 cm (12.8–13.8 in). Big brown bats are insectivorous, consuming a diverse array of insects, particularly night-flying insects, but especially beetles. [4]
The general assembly of North Carolina considered a bill in 2007 that would have made Rafinesque's big-eared bat as its state bat. The bill passed 92-15, but died in the state senate. [3] In 2020, the big brown bat was designated the official state mammal of the District of Columbia. [4]

Since 2000, all the five human rabies cases contracted domestically in Canada were acquired from bats. [50] Fewer than 2% of bats in Canada are rabid, 95% of which are big brown bats.
