Description: A medium-sized (wingspread: 26-30 cm [10 - 12 in.]; mass:
5 - 7 g [0.18 - 0.25 oz]), buffy brown bat with relatively long black
ears. A
fringe of short hairs that project backward from the edge of the tail
membrane is a diagnostic feature since this is the only species of bat in
Nevada with a fringe of hairs on the tail membrane. Fringed myotis are
colonial but male and female do so separately. Nursery colonies exceed
several hundred individuals. A single offspring is born during June or July.
Diet: Forages in the early evening, flying slowly and feeding
on a variety of insects including moths, caddis flies, and flies.
Habitat: Desert scrub, pinyon-juniper, and coniferous forest habitats,
usually at elevations of 1,200 - 2,100 m (4,000 - 7,000 ft). Roosts in
caves, mines, rock crevices, trees, and buildings.
Range: This species occurs across the southern half of Canada and
southward through most of the United States. In Clark County, Nevada,
this species occurs predominantly at higher elevations but is found at
low elevations during spring and fall migration. Probably migrates south
for the winter.
