Evening bats roost in tree hollows and building eaves, and Texas’s records spread across 86 counties, led by Bexar, Williamson, Dallas, and Tarrant, wherever mature trees supply both cavities to roost in and the insects overhead this species hunts at dusk.

Reports peak hard in June, about double May’s count, and stay high in July, which lines up with when maternity colonies are active and easiest for surveyors to find. With 462 Texas records, the species sits at the 75th percentile among ranked Texas mammals, common by that measure though still modest in raw count next to more frequently reported bats. NatureServe lists it S5, Secure statewide.
