gloomy scale picgloomy scale 3 I noticed this maple tree today while taking a walk around inner Charlotte. The small bumps on the bark of this limb are gloomy scale insect shells. Gloomy scale is an invasive insect that attaches itself to the limbs of the tree and feed on the sugary sap just below the bark. In the late spring season, hundreds of scale insect eggs hatch from each existing shell and continue the cycle of infestation. Over time, the scale activity drains the tree of its energy and causes the tree to die. This photo shows a serious case of scale infestation. The black color that you see is mold growing on the excessive sticky sap excreted by the scale. We call this black substance “sooty mold”, due to its sooty black appearance. Many urban maple trees in the Charlotte communities are infested with gloomy scale. Winter is a great time to discover this issue since the trees are free of leaves.
