Long-legged Myotis

_Specimens examined_ (43).--2 mi. N, 5 mi. W Ludlow, 4; NW 1/4 sec. 15,

R. 5 E, T. 22 N, 12; 10 mi. S, 5 mi. W Reva, 27.

The long-legged myotis is one of the commonest bats of the wooded

buttes, accounting for almost half of all chiropterans taken in these

areas. Most of our specimens were shot as they foraged among trees and

over water in the evening; a few were captured in mist nets.

Uteri of eight females obtained in the period May 23 to 31 were

enlarged; two females collected on June 29 carried single embryos that

measured 20 and 22. A lactating female was taken on August 3, but three

other adult females taken early in the same month evidenced no

reproductive activity. Testes measured 2 to 4 in three May-taken males

and 4 in each of two from June.

Two males obtained June 16 and 23 were molting as evidenced by new hairs

under the old pelage over much of the body.

_Myotis volans_ that we examined for ectoparasites harbored chiggers,

_Leptotrombidium myotis_ (Ewing), and fleas, _Myodopsylla gentilis_

Jordan and Rothschild.
