Parthenolecanium (= Lecanium) corni (Bouche)
EUROPEAN FRUIT LECANIUM (Brown Soft Scale)

Hosts: European fruit lecanium has a very wide host range including many deciduous trees and shrubs. Elm and stone fruits (Prunus) are the most common hosts.

European fruit lecanium is a soft scale that feeds on the phloem of small branches. European fruit lecanium is also capable of producing large amounts of honeydew, which can be a serious nuisance problem and favor the growth of sooty mold.

Coinfestations with other scales can occur, particularly mixed populations with European elm scale. The European elm scale can be identified by having a covering that is dome-shaped, dark brown, and fairly smooth.
