The genus name “Calligrapha” is a reference to the beautiful calligraphic script on the backs of many species. This species’s coloration is not quite as script-like, but it definitely still appears painted. These beetles are most common in the Northern Rockies of Montana, Alberta, and Saskatchewan, but, according to some older sources, their range is far broader, stretching from Nebraska to California to Alaska. If you have photographs of these beetles please contact me to supplement our scientific understanding of their distribution!
