Idaho’s Yuma myotis records concentrate in the central mountains, around the Frank Church-River of No Return Wilderness, the Sawtooth National Recreation Area, and the Boise National Forest, wherever the Salmon River and its mountain lakes and streams give this water-loving bat calm surface water to hunt over.
It flies low and fast just above ponds and slow river stretches, snatching insects right at the water’s surface, and it roosts nearby in caves, rock crevices, bridges, or buildings so it never has to travel far between shelter and a meal.
Records here are rare overall, but reports spike sharply in May before tapering through summer into a smaller bump in October, tracking when maternity colonies settle in and insects are most active over these mountain waters.
