European fruit lecanium

Parthenolecanium corni

The European fruit lecanium, also known as the brown apricot scale, occurs throughout California but is rarely a problem. This scale has one generation per year. It overwinters as a nymph on twigs and small branches. In spring, it grows rapidly and secretes large amounts of honeydew. The adult cover is domed, shiny brown, and about 0.25 inch (6 mm) in diameter with several ridges along the back. The females are parthenogenic (reproduce without being fertilized) and lay many eggs, filling the entire space beneath the covers. They die after egg production.
