Taxonomy and etymology

It was described in 1776 by German zoologist Philipp Ludwig Statius Müller. He initially placed it in the genus Vespertilio, with the name Vespertilio borealis.[2] It was not placed into its current genus Lasiurus until the creation of the genus in 1831 by John Edward Gray.[3] Its species name "borealis" is Latin in origin, meaning "northern." Of the species in its genus, the eastern red bat is most closely related to other red bats, with which they form a monophyly. Its closest relatives are the Pfeiffer's red bat (Lasiurus pfeifferi), Seminole bat (L. seminolus), cinnamon red bat (L. varius), desert red bat (L. blossevillii), saline red bat (L. salinae), and the greater red bat (L. atratus).[4]

Eastern red bat (female), roosting


The eastern red bat has distinctive fur, with its back brick red or rusty red and frosted with white. Individual hairs on its back are approximately 5.8 mm (0.23 in), while hairs on its uropatagium are 2.6 mm (0.10 in) long. Fur on its ventral surface is usually lighter in color, while the shoulders may appear white. Females are usually lighter in color than the males. Its entire body is densely furred, including its uropatagium. It is a medium-sized member of its genus, weighing 7–13 g (0.25–0.46 oz) and measuring 109 mm (4.3 in) from head to tail. Its ears are short and rounded, with triangular tragi. Its wings are long and pointed. Its tail is long, at 52.7 mm (2.07 in) long. Its forearm is approximately 40.6 mm (1.60 in) long. Its dental formula is, for a total of 32 teeth.[3]


The aspect ratio and wing loading of eastern red bat wings indicates that they fly relatively quickly and are moderately manoeuvrable.[3] Eastern red bats are insectivorous, preying heavily on moths, with other insect taxa also consumed. They consume known pests, including gypsy moths, tent caterpillar moths, Cydia moths, Acrobasis moths, cutworm moths, and coneworm moths.[5]

Range and habitat

The eastern red bat is widely distributed in eastern North America and Bermuda.[6] It generally occurs east of the Continental Divide, including southern Canada and northeastern Mexico. In the winter, it occurs in the southeastern United States and northeastern Mexico, with greatest concentrations in coastal areas. In the spring and summer, it can be found in the Great Lakes region and the Great Plains region. Unlike the closely related hoary bat, males and females have the same geographic range throughout the year.[7] Formerly, some authors included the western United States, Central America, and the northern part of South America in its range,[3] but these populations have since been reassigned to the desert red bat, Lasiurus blossevillii.[6]


The eastern red bat is evaluated as least concern by the IUCN, the lowest-priority conservation category. It meets the criteria for this designation because it has a wide geographic range, large population size, it occurs in protected areas, it tolerates some habitat disturbance, and its population size is unlikely to be declining rapidly.[1] Eastern red bats and other migratory tree bats are vulnerable to death by wind turbines via barotrauma.[8] The eastern red bat has the second-greatest mortality from wind turbines, with hoary bats most affected.[9] While it has been documented carrying the spores of Pseudogymnoascus destructans, the fungus that causes white-nose syndrome, no individuals have been observed with clinical symptoms of the disease.[10]

Barbastella is a small genus of vespertilionid bats. There are five described species in this genus.

Cinnamon red bat

The cinnamon red bat (Lasiurus varius) is a species of bat from the family Vespertilionidae. It is often listed as a synonym of the eastern red bat or the desert red bat, but is distinct.

Desert red bat

The desert red bat (Lasiurus blossevillii), also known as the western red bat, or southern red bat, is one of many species of bats. This particular one is from the family Vespertilionidae, which is the largest bat family. This species and its relative Lasiurus borealis are sometimes just referred to as red bats.


Eimeria is a genus of apicomplexan parasites that includes various species capable of causing the disease coccidiosis in animals such as cattle, poultry, and smaller ruminants including sheep and goats. Eimeria species are considered to be monoxenous because the life cycle is completed within a single host, and stenoxenous because they tend to be host specific, although a number of exceptions have been identified. Species of this genus infect a wide variety of hosts. Thirty-one species are known to occur in bats (Chiroptera), two in turtles, and 130 named species infect fish. Two species (E. phocae and E. weddelli) infect seals. Five species infect llamas and alpacas: E. alpacae, E. ivitaensis, E. lamae, E. macusaniensis, and E. punonensis. A number of species infect rodents, including E. couesii, E. kinsellai, E. palustris, E. ojastii and E. oryzomysi. Others infect poultry (E. necatrix and E. tenella), rabbits (E. stiedae) and cattle (E. bovis, E. ellipsoidalis, and E. zuernii). For full species list, see below.

The most prevalent species of Eimeria that cause coccidiosis in cattle are E. bovis, E. zuernii, and E. auburnensis. In a young, susceptible calf it is estimated that as few as 50,000 infective oocysts can cause severe disease. Eimeria infections are particularly damaging to the poultry industry and costs the United States more than $1.5 billion in annual loses. The most economically important species among poultry are E. tenella, E. acervulina, and E. maxima. The oocysts of what was later called Eimeria steidai were first seen by the pioneering Dutch microscopist Antonie van Leeuwenhoek (1632–1723) in the bile of a rabbit in 1674. The genus is named after the German zoologist Theodor Eimer (1843–1898).

De Winton's long-eared bat (Laephotis wintoni)


Lasiurus is the genus comprising hairy-tailed bats. The generic name Lasiurus is derived from the Greek lasios (hairy) and oura (tail). It contains some of the most attractive bats (Chiroptera) in the whole continent of North America, including such species as the eastern red bat, L. borealis, and the hoary bat, L. cinereus. They are very robust and long-winged, with fast and strong flight; several species fly during parts of the day, especially when migrating south in autumn. The hoary bat and red bat will often fly in daylight during winter.

When roosting, this group is also interesting as they hang from twigs, usually hidden by leaves in trees, and do not use caves. The northern species, such as the red and hoary bats, have particularly thick and dense fur for extra insulation, and may migrate south in winter, although winter roosting sites can still be quite cool.

They are, as a genus, unusual, being the only bats apart from the parti-coloured bat Vespertilio murinus to possess an extra pair of nipples (four in total). This allows them to suckle more than the usual one pup per season that most bats produce, with two or three being common and sometimes four produced, though more rarely.

Minor red bat

The minor red bat (Lasiurus minor) is a species of bat from the family Vespertilioninae. It is found in the Bahamas, Dominican Republic, Haiti, and Puerto Rico, though there are only six known individuals in the latter. Hurricanes, habitat destruction, and human population growth are several factors leading to a decreasing population trend, and the minor red bat is listed as vulnerable by the IUCN Red List due to ongoing population reduction and a small geographic range. The minor red bat is a solitary, insectivorous species that forages in open areas and rests among the leaves of a tree. It is a swift flier, though it is not highly maneuverable. The minor red bat is possibly conspecific with the Seminole bat, Eastern red bat, and Desert red bat.

Tragus (ear)

The tragus is a small pointed eminence of the external ear, situated in front of the concha, and projecting backward over the meatus. It also is the name of hair growing at the entrance of the ear. Its name comes from Ancient Greek tragos, meaning 'goat', and is descriptive of its general covering on its under surface with a tuft of hair, resembling a goat's beard. The nearby antitragus projects forwards and upwards.Because the tragus faces rearwards, it aids in collecting sounds from behind. These sounds are delayed more than sounds arriving from the front, assisting the brain to sense front vs. rear sound sources.In a positive fistula test (for the presence of a fistula from cholesteatoma to the labyrinth), pressure on the tragus causes vertigo or eye deviation by inducing movement of perilymph.


The Vespertilioninae are a subfamily of vesper bats from the family Vespertilionidae.
