Description

A powdery white waxy covering appears in the crevices of the bark of beech trees, under which small sap feeding scale insects live. The trees are rarely killed by this, but it allows the Beech Bark disease to enter the wound and this then eventually kills the tree. Picture by Joseph O'Brien, USDA Forest Service, Bugwood.org
