Long-eared myotis records in Utah concentrate in the state’s northern high country, the Uinta-Wasatch-Cache National Forest and the broader Uinta and Wasatch ranges. This bat’s oversized ears suit slow, careful hunting around tree bark, rock crevices, and broken ground rather than open water, so the mountain forest fits its actual habits better than desert canyon country would.

Utah reports are almost entirely a summer phenomenon: 64 of the state’s 138 records land in July alone, with June and August also active and every other month close to silent. That pattern likely reflects both the bat’s own activity and when researchers are out running mist nets, not a true absence the rest of the year.

Most Utah records come from GBIF survey data rather than iNaturalist photos, unsurprising for a nocturnal bat that’s rarely seen in daylight. NatureServe ranks it S3, Vulnerable, in the state.
