General Comments

Scale insect which feeds on pine trees and some other conifers. Native to Europe, the first UK population was found at one location in London in 2023 on pine trees in an urban environment. Limited evidence of impacts in the native and introduced range of the pest, and it appears to only cause noticeable impacts in urban environments, where hosts are exposed to other environmental stressors.
