This bat is brown to reddish brown and has relatively long forearms. It gets its name from the fringe of hairs along the bottom of its tail.
It roosts in trees, snags, buildings, caves, rocks, cliffs and bridges. It likes beetles and moths but will eat spiders and crickets.
The fringed myotis occurs in the Coast Range from Jackson County to Clatsop County and in the northeastern corner of the state. It's an Oregon Conservation Strategy Species in seven of the nine ecoregions.
