The long-eared myotis is not uncommon in and around wooded buttes. The
species may be mostly limited to these areas; an individual of unknown
sex found dead in a small stream southeast of Harding (several miles
south of the East Short Pine Hills) is the only specimen not taken in
such a situation. North of Camp Crook, on the eastern edge of the Long
Pine Hills, several _M. evotis_ used an abandoned shed as a night roost
in the summer of 1970; one was captured in a bat trap set at one of the
entrances to the shed.
Females obtained on May 29 and June 17 and 19 carried single embryos
that measured 3, 14, and 15, respectively. A male young of the year
taken on August 6 was nearly of adult size. Testes of two May-taken
males measured 4 and 2, whereas those of one taken on July 17 and
another captured on August 3 measured 6.0 and 7.5, respectively.
Of seven adults collected in the period August 3 to 6, three females and
two of four males were in fresh pelage; molt was nearly completed on the
two remaining males. A male taken in mid-July was in an early stage of
molt. New pelage is pale yellowish brown in contrast to the golden brown
pelage of specimens taken in May and June.
Chiggers, _Leptotrombidium myotis_ (Ewing), were found on the ears of
one long-eared myotis.
