Pipistrellus subflavus subflavus (F. Cuvier)
Eastern Pipistrelle
V[espertilio]. subflavus F. Cuvier, Nouv. Ann. Mus. Hist. Nat. Paris, 1:17, 1832, type from eastern United States, probably Georgia.
Pipistrellus subflavus, Miller, N. Amer. Fauna, 13:90, October 16, 1897.
Distribution in Nebraska.—Known from limestone quarries in Cass and Sarpy counties; probably ranging throughout eastern Nebraska.
Records of occurrence.—Specimens examined, 34, as follows: Cass Co.: 1 mi. NE Louisville, 4. Sarpy Co.: 1/2 mi. W Meadow, 30 (some of these specimens have been deposited in other collections as follows: Private Collection of P. H. Krutzsch, 3; Private Collection of W. G. Frum, 2; Univ. Kansas Mus. Nat. Hist., 4; Univ. Nebr. State Mus., 4).
Remarks.—This bat is the most common of the four species that are known to inhabit the quarries in Cass and Sarpy counties. Individuals have been found both in drill holes and clinging to the walls of the quarries. We have always found this bat to be solitary while in hibernation.
Eptesicus fuscus fuscus (Beauvois)
Big Brown Bat
Vespertilio fuscus Beauvois, Catal. Raisonné Mus. Peale, Philadelphia, p. 18, 1796, type from Philadelphia, Philadelphia Co., Pennsylvania.
Eptesicus fuscus, Méhely, Magyarország denevéreinek monographiája (Monographia Chiropterorum Hungariae), pp. 206, 338, 1900.
Distribution in Nebraska.—Eastern part of state.
Records of occurrence.—Specimens examined, 23, as follows: Adams Co.: Hastings, 1 (Hastings Museum, Hastings, Nebraska). Cass Co.: 1 mi. NE Louisville, 6; Plattsmouth, 1 (Univ. Nebr. State Mus.). Sarpy Co.: 1/2 mi. W Meadow, 15 (Univ. Nebr. State Mus., 7).
Remarks.—We have observed this bat hibernating in the limestone quarries of Cass and Sarpy counties, where it was commonly found in drill holes or clinging to the ceiling or walls. We have always found this bat to be solitary while in hibernation, with one exception. On January 31, 1949, a male and female were found in the same drill hole in the Cass County quarry. The jolt of being knocked from the hole separated the two bats, and upon examination the penis of the male was noted to be extended and erected, indicating that the pair might have been in the act of copulation.
Eptesicus fuscus pallidus Young
Big Brown Bat
Eptesicus pallidus Young, Proc. Acad. Nat. Sci. Philadelphia, p. 408, October 2, 1908, type from Boulder, Boulder Co., Colorado.
Eptesicus fuscus pallidus, Miller, Bull. U. S. Nat. Mus., 79:62, December 31, 1912.

Remarks.—A colony of approximately 100 of these bats was discovered in the
