Cassius Blues typically arrive in Alabama by accident, hitching a ride as eggs, caterpillars, or chrysalides on one of their favored host plants, Blue Plumbago (Plumbago auriculata). Often sold at garden centers and in box stores, Blue Plumbago plants are generally shipped from wholesale nurseries in south Florida where Cassius Blues commonly occur.
