REVISION OF MOTHS OF CARPOSINIDAE

Map 2. — Distribution of Carposina (Carposina) fernaldana. 



DRD 1799; in the United States National Museum. 



Type-locality. — New Brighton, Pennsylvania, (lectotype). 



Host. — Rosaceae: ''Crataegus sp., larvae in fruits" (from specimen 

 label). Saxifragaceae : "larvae in nearly ripe currents [Rihes sp.]," 

 (Forbes, 1923 p. 515).
