Comments: This species is primarily Floridian and it may occur in North Carolina as only a stray; in South Carolina, it has been recorded only along the Coast near Charleston (Snyder, 2017). More sampling is needed to determine its status as a resident species, and more information is needed on its overall distribution, host plants, and habitat associations before its conservation status can be assessed.
