Fringed Myotis

About the Fringed Myotis

The fringed myotis (Myotis thysanodes) is a species of vesper bat that is found in British Columbia, Mexico, and the western United States. Myotis thysanodes, or the fringed myotis, has the shortest ears of the long-eared myotis group. The fringed myotis gets its name from the distinct fringe of short, wire-like hairs found on the membrane between its hind legs. With a lifespan that can reach upwards of 18 years, this species has an average total body length of roughly 85 millimetres (3.3 in) and an average weight of 8.8 grams (0.31 oz). Ear length is about 16.5 millimetres (0.65 in) and they project roughly 5 millimetres (0.20 in) beyond its snout. The hind foot is 8–9 millimetres (0.31–0.35 in) and the tail is 37–40 millimetres (1.5–1.6 in). Sexual dimorphism is seen in this species with males being much smaller than their female counterparts. They possess a pelage that is full and tends to be light yellow-brown or olive on the back with an off-white color on its underside. Northern populations tend to have darker coloration. The dental formula of Myotis thysanodes is 2.1.3.33.1.3.3.
