The complete county distribution, spread across 5 Ohio counties. Every occurrence record falls in one county, so these sum to the total. Counties from GBIF and US Census boundaries.

Ohio has only 5 evening bat records since 2000, one each from Clark, Montgomery, Logan, Ross, and Cuyahoga counties, too few to say where the species actually concentrates. It forages low over water and along woodland edges and roosts in tree cavities and buildings close to that kind of foraging ground.

The few dated records fall between April and July, a window that lines up with the warmer months when evening bats are most active and easiest for people to notice, rather than proving the species disappears the rest of the year. Ohio sits near the northern edge of a range centered farther south and east in the United States, which helps explain why records here are sparser than in states well within its core range. Its NatureServe status in Ohio is unranked, meaning there isn’t enough information on file to assign a formal conservation grade.
