The complete county distribution, spread across 14 Idaho counties. Every occurrence record falls in one county, so these sum to the total. Counties from GBIF and US Census boundaries.

Long-eared myotis records in Idaho reach from the lava fields of Craters of the Moon National Monument to the high country of the Sawtooth National Recreation Area and the Frank Church-River of No Return Wilderness, a spread that fits a bat equally at home foraging over open desert and dense forest.

Reports peak in July and August, when summer roost and maternity-colony activity is highest, though with just 27 total records the overlay’s seasonality field is flagged as thin. NatureServe ranks the species S3, Vulnerable, in Idaho.
