The Queen butterfly is found in North America around Texas and the states bordering the Gulf of Mexico. Rarely, individuals will go north and in 2002 and 2003, some individuals were located in the Philadelphia and Reading areas of Pennsylvania (Monroe, James and David Wright. 2017. Butterflies of Pennsylvania, a field guide. University of Pittsburgh Press). It is part of the same genus as the Monarch butterfly, Danaus, and has seven recognized subspecies (Wikipedia).
