In the cave myotis, Myotis velifer
, this loss is more pronounced in females (22 %) than in males (20 %) (Caire & Loucks 2010).

One is a maternity colony comprised of approximately 1.5 million Brazilian free-tailed bats (Glass, 1982); the other is a mixed colony of male Brazilian free-tailed bats and cave myotis (Myotis velifer
) totaling approximately 500,000 individuals (John Gay, pers.
Eighteen different OPs were detected in guano from maternity roosts of cave bats (Myotis velifer
) in Texas (Land 2001).
. -- The cave myotis is distributed throughout much of western Texas with the exception of the westernmost and northernmost panhandle region (Schmidly 2004).
Four specimens each of Pipistrellus subflavus, Eptesicus fuscus, Myotis velifer
and Tadarida brasiliensis were immersion fixed in 3% glutaraldehyde in phosphate buffered saline (PBS) overnight.
Following these actions, there was an immediate increase in numbers of cave myotis (Myotis velifer
), an insect-feeding bat that shares the roosts of lesser long-nosed bats.
A single cave myotis, Myotis velifer
, from Woodward County in western Oklahoma with a white crustal growth, was submitted in early May 2010 to the United States Geological Service (USGS) National Wildlife Health Center (NWHC) for determination if the growth was Pd.
