A bat of a large family (Vespertilionidae) that includes most of the typical insectivorous bats of north temperate regions.
- The vespertilionid genus Myotis has the widest distribution of all bat genera.
- For comparison, respirometric data were also obtained from Nyctalus noctula, a hibernating vespertilionid bat of similar body size and convergent foraging habits.
- Like many vespertilionid bats, females of some rhinolophid species mate during the fall and store the sperm over the winter, conceiving and gestating young beginning in the spring.
