Global Range: (<100-200,000 square km (less than about 40-80,000 square miles)) Known from about half the total range of the foodplant in Texas, a nearly contiguous line of counties: Aransas, Bee, Bexar, Cameron, Hidalgo, Jim Wells, Karnes, Kinney, Kleberg, Medina, Nueces, San Patricio, Starr, and Wilson in Texas and from four places in Tamaulipas, Coahuila, and Nuevo Leon, Mexico. Recent efforts to relocate the species in ten of these counties have been unsuccessful, as were efforts in the 1950s and since in some others. Only post-1980 record is for Kinney Co. in 2008. The habitat of that one colony might be the current range.
