About this list
Compiled from published records, museum material, and survey reports, and recorded to 33 counties. Coordinates are never published; distribution is published generalized to county and karst region. See the Data Sensitivity Policy.
Absence from this list does not mean absence from the ground. Most caves have never been surveyed, and subterranean fauna is consistently under-recorded. If you know of a species here that is missing, please tell us.
