Kazial KA and Masters WM: Female big brown bats, Eptesicus fuscus
, recognize sex from a caller's echolocation signals.
Professor of Life Sciences at Indiana State University, estimates in his article, "Food of the big brown bat Eptesicus fuscus
from maternity colonies in Indiana and Illinois," that a colony of 150 big brown bats could eat enough cucumber beetles to equal "the potential destruction of 33,000,000 rootworms.

Tales of spooks may hold a spark of truth, for recent research implies intelligence directs the lights: Bioluminescent flying predators may be hunting at night and catching a few unlucky Big Brown Bats: Eptesicus fuscus
Other bats captured were (number of males/ number of females): Eptesicus fuscus
(8/0), Myotis californicus (2/1), Myotis thysanodes (3/0), Myotis volans (1/2), Antrozous pallidus (5/0), Corynorhinus townsendii (0/6), Lasiurus cinereus (3/1), and Pipistrellus hesperus (1/0).
Thus far we have documented six species of bats to include Pipistrellus subflavus, Nycticeius humeralis, Lasiurus borealis, Lasiurus seminolus, Eptesicus fuscus
, and Tadarida brasiliensis.
For Eptesicus fuscus
and Myotis septentrionalis, earlier dates were obtained for spring and later dates for autumn.

sampled in 2002 consumed strictly soft-bodied insects from 17-20 May, then later transitioned to hard-bodied insects during 28 May-9 August, and eventually appeared to return to a dominant prey item of soft-bodied insects on 20 September.

They found that the communities varied greatly among bat species present, and even between buildings in the case of Eptesicus fuscus
brasiliensis, Eptesicus fuscus
, Lasiurus borealis, Lasiurus cinereus, Nycticeius humeralis, Parastrellus hesperus, Perimyotis subflavus, Antrozous pallidus, Myotis grisescens, and Myotis velifer.
The 412-nt sequence of this virus was most closely related to alphacoronaviruses detected in Eptesicus fuscus
bats in North America (82% nt identity), Myotis australis bats in Australia (77% nt identity), Miniopterus bats in Kenya (77% nt identity), and Rhinolophus bats in Hong Kong (77% nt identity) (Figure).
Any of the following bats could occur: the northern myotis Myotis septentrionalis, the Indiana myotis Myotis sodalis, the big brown bat Eptesicus fuscus
, and the hoary bat Lasiurus cinereus.
