Occurrence Notes
One specimen has been collected on the south rim. Data soure: Vernon Bailey. 1935 "Mammals of the Grand Canyon Region" Grand Canyon Natural History Bulletin, I (Web Link: http://npshistory.com/nature_notes/grca/nhb-1c.htm). However, while doing bat work in Grand Canyon from 1995-2015 park biologists have never recorded this species. It is possible that this species was extirpated or that is exceedingly rare.

However, while doing bat work in Grand Canyon from 1995-2015 park biologists have never recorded this species. It is possible that this species was extirpated or that is exceedingly rare. The species is heavily dependent on insects in riparian areas. It is possible the the Hoover Dam may have an impact on insect abundance and timing of insect releases in the park.
