Phyllonorycter cerasicolella

Cherry midget

Description

Phyllonorycter cerasicolella is a leaf-mining moth from the family Gracillariidae, primarily associated with cherry trees (Prunus spp.), including cultivated species. The larvae create mines on the underside of leaves, which can affect the aesthetic appearance of trees and, in high numbers, contribute to premature leaf fall. The species occurs across most of Europe, except northern Scandinavia. It produces two to three generations per year, with adults emerging in spring and late summer. The larvae overwinter within the mines and pupate in early spring. Besides cherries, the species can occasionally mine leaves of apple trees (Malus spp.) when grown near Prunus.

Symptom

The mine is a lower-surface tentiform blotch, usually located between two lateral veins. It has a smooth, unwrinkled surface. Infected leaves often show localized swelling and slight discoloration, with the epidermis remaining intact and silvery in appearance.
