It is most commonly collected on composites (Asteraceae) and legumes (Fabaceae). Four species of Crypticerya other than C. rosae (Riley & Howard) and C. genistae have been intercepted at a U. S. port-of-entry including: C. littoralis (Cockerell) (Mexico, on Carica, Chamaedorea, and Persea; Guatemala, on Chamaedorea); C. montserratensis Riley & Howard (Colombia, on orchid; Dominican Republic, on Annona; Guatemala and Mexico, on Chamaedorea); C. similis Morrison (El Salvador, on Laelia); and C. zeteki (Cockerell) (El Salvador, on orchid).
