Recluse Distribution & Map

This map is based on data collected by arachnologists and is provided courtesy of Rick Vetter.  Generally, recluses can be expected to be uncommon at the margins of this range.  Rarely, they are found outside of this normal distribution in very localized areas.  Such rare encounters should not be interpreted as a broadening of the species typical range or as an indication of large populations throughout the area in which the unusual sighting was recorded.
