Nycticeius humeralis (Rafinesque 1818)

Evening Bat

The evening bat, Nycticeius humeralis , generally is considered a species of forested areas, especially along rivers, and has been known to utilize buildings and other manmade structures ( Schmidly 2004). This species commonly is found throughout most of the eastern United States and has traditionally occupied East Texas ranging from the Red River in the north to the Rio Grande in the south. Collection of the evening bat in Val Verde, Presidio, and Tom Green counties, as well as previous DSHS records in Yoakum and Bailey counties, suggest a westward expansion of the species throughout Texas ( Dowler et al. 1999; Ammerman et al. 2012). This species has not been documented in New Mexico ( Reid 2006). Therefore, these West Texas records represent the western range limit of the species. Nineteen new county records help define the distribution of N. humeralis within Texas. Four of the counties ( Guadalupe, Nueces, Smith, and Tarrant) were previous DSHS records.

Therefore, these specimens serve as a voucher for this county.
