Cameraria caryaefoliella is a moth of the Gracillariidae family. It is known from Quebec, Canada, and the United States (including Georgia, Illinois, Florida, Kentucky, New York, Texas, Vermont, Wisconsin, Connecticut and Pennsylvania). The wingspan is 6–7 mm. Adults are small and have reddish-orange forewings with three silvery-white bands. There are three generations per year. Larvae pupate in flat, oval cocoons of densely woven silk within the upper blotch mine. The pupa wriggles free of the cocoon and breaks through the upper leaf surface.
