The complete county distribution, spread across 10 Utah counties. Every occurrence record falls in one county, so these sum to the total. Counties from GBIF and US Census boundaries.

Utah’s spotted bat records come almost entirely from Glen Canyon National Recreation Area and the Sevier Desert basin-and-range country of west-central Utah, cliff-lined terrain that fits a bat that roosts in rock crevices and forages over open desert. Fishlake National Forest sits at the edge of that pattern.

Only 22 records exist statewide, one of the thinnest totals of any Utah mammal here, with the last confirmed sighting in August 2021. Reports cluster in summer, peaking in July with 6 records, when its low, human-audible echolocation calls are most likely to be noticed over open ground at dusk.

Despite that low local record count, NatureServe ranks the spotted bat S4, Apparently Secure, in Utah, since sparse detections are typical for a species this specialized to cliff roosts and hard to survey.
