Cydia (moth)

"Lasperesia" and "Lespeyresia" redirect here. These are misspellings of Laspeyresia, which was invalidly established for the genus Cydia and actually refers to the noctuid moth genus Laspeyria.

Cydia is a large genus of tortrix moths, belonging to the tribe Grapholitini of subfamily Olethreutinae. Its distinctness from and delimitation versus the tribe's type genus Grapholita requires further study.

Moths in this genus are generally small and dull brown; their caterpillars are yellow or white and wormlike. Cydia includes many species of economic importance due to the damage their caterpillars inflict as pests of agricultural crops, especially fruit and nut trees. On the other hand, some Cydia species have been used for biological control of invasive weeds, and many of these small moths and their caterpillars are an important food source for other animals. A few species from the Hawaiian Islands are suspected to be extinct due to disappearance of their foodplants.
