The complete county distribution, spread across 2 Texas counties. Every occurrence record falls in one county, so these sum to the total. Counties from GBIF and US Census boundaries.

Long-legged myotis records tied to Texas come entirely from GBIF specimen data, with zero iNaturalist photos among the 50 total, a gap that fits a bat that roosts in tree cavities and rock crevices and rarely crosses paths with casual observers. Nearly all are from the Trans-Pecos mountains, 46 from Jeff Davis County in the Davis Mountains and 4 from Brewster County, as you’d expect from a species better known as a mountain and conifer-forest bat.

NatureServe ranks it S1, Critically Imperiled, in Texas, a much steeper concern than its G4, Apparently Secure, global status, making it one of the state’s rarer bats on paper. The records bunch in May and June, 23 and 19 of the 50, which more likely marks when bat surveys were run in the mountains than a real seasonal signal.
