The complete county distribution, spread across 20 New Mexico counties. Every occurrence record falls in one county, so these sum to the total. Counties from GBIF and US Census boundaries.

New Mexico has 98 fringed myotis records since 2000, most of them carried by GBIF rather than iNaturalist photos, spread across 20 counties led by Cibola and Catron. The species is named for a fringe of stiff hairs along its tail membrane, and it roosts in caves and buildings while foraging over desert, grassland, and woodland, a mix reflected in records from Cebolla Wilderness Area, El Morro National Monument, Chaco Culture National Historical Park, and Organ Mountains-Desert Peaks National Monument, sandstone and volcanic country full of the cliffs and crevices this bat uses for roosts.

Monthly counts swing hard, from none in winter to 23 in both May and June, with a second rise to 19 in September, tracking when the bat is flying and active rather than any change in how many actually live here. NatureServe rates it apparently secure in the state.
