Long-eared myotis carry noticeably larger ears than most of Arizona’s other small brown bats, an adaptation that helps them pick up faint echoes while gleaning moths and beetles directly off foliage rather than only catching insects in open air. The conifer forest around Grand Canyon National Park, Coconino National Forest, and Kaibab National Forest gives them the kind of understory hunting ground this style of foraging depends on.
Every record on file falls between June and August, with July the clear high point, tracking peak summer maternity-roost activity when females and young are most active on the wing. Arizona’s occurrence count sits in the rare tier statewide, consistent with a forest bat that’s active well after dark and easy to miss even where it’s genuinely present.
