The complete county distribution, spread across 18 Kansas counties. Every occurrence record falls in one county, so these sum to the total. Counties from GBIF and US Census boundaries.

Only a handful of tricolored bats have been logged in Kansas, and most of what exists comes from specimen and survey work rather than photos: 206 GBIF records against just 8 research-grade iNaturalist observations. That split makes sense for a bat this small and this easy to miss on the wing; most Kansas detections likely trace back to mist-net surveys or hibernaculum counts rather than casual sightings.

Cheyenne Bottoms and Quivira National Wildlife Refuge turn up in the reports for their calm, insect-rich water, exactly the kind of foraging edge this species favors on summer evenings. Reports are scattered across nearly every month with no dominant peak, August has the most entries, but just three, which fits a species logged so rarely that any single report shifts the picture.

Kansas ranks it in the bottom fifth of species by report volume here, and NatureServe lists it as Apparently Secure in-state even though white-nose syndrome has devastated populations in caves farther east.
