Dots in Texas and Florida show county records; dots in California are placed as in Fig. 1 of Weissman et al 1980.

Computer-generated distribution map, produced from records in a database available on this site.

(Note: Monroe County, Florida, includes the southwest portion of the tip of mainland Florida and the upper and lower keys. These three parts of that county are mapped separately in the "dot maps" but not in the computer-generated distribution maps, which are strictly at the county level.)
