Distribution and ecology. The species is known from Québec and New York to Manitoba and Nebraska and south to Florida, Texas and Mexico, Panama Canal Zone and Nicaragua, and possibly from Argentina, Bolivia and Venezuela ( Roback 1971: 32, 1974b: 9, 17; Oliver et al. 1990: 8; Epler 2003, 2006; Caldwell 2009; Ashe & O’Connor 2009: 142).
