Yuma myotis records in Texas show up almost entirely in the mountain and canyon country of the Trans-Pecos, with Big Bend, the Guadalupe Mountains, and the Davis Mountains anchoring the record set. This small bat forages low over ponds and streams at night and roosts in caves, mine shafts, and rock crevices, so those sky-island canyons are a natural fit for it.
Records lean heavily toward June, which holds 65 of the 164 documented sightings. That’s likely a mix of maternity-roost activity and more people watching for bats in early summer, not proof the species disappears the rest of the year.
NatureServe ranks it S3, Vulnerable, in Texas even though it’s Secure (G5) across its full range, a reminder that a species can be common continent-wide while still carrying real state-level concern here.
