Long-legged myotis (Myotis volans)

Species Profile

BatPicture.

Myotis volans are known to use caves in CO.  Siemers (2002) documented this species using 5 caves during surveys with solitary individuals typical.  Navo et al. (2002) documented this species swarming at a cave in CO where Siemers (2002) identified 76 individuals.  Because this species is occasionally known to roost within caves in large numbers improper gating could have significant affects on local populations across the state.
