The complete county distribution, spread across 4 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 are thin and come entirely from GBIF specimen data, with zero iNaturalist photos among the 19 total, a gap that fits a bat that roosts in tree cavities and rock crevices and rarely crosses paths with casual observers. The listed locations span Big Thicket, Davy Crockett National Forest, and Balcones Canyonlands, though this species is better known elsewhere as a mountain and conifer-forest bat, so these Texas records likely mark scattered edge-of-range detections rather than a core population center.

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. What little timing data exists points to a June peak, but with only 19 records total, that’s a hint, not a real seasonal signal.
