sooty mold caused by spotted lanternfly
Sooty mold, such as shown in this example at the base of a tree, results from a combination of sap flows caused by the spotted lanternfly (Lycorma delicatula) and honeydew excreted by the insect. (Photo credit: Lawrence Barringer, Pennsylvania Department of Agriculture, Bugwood.org)
I just killed Two spotted lantern flies on October 20, 2020 I didn’t realize they were this far north. The lantern flies were killed in Thornhurst Pennsylvania
The lanternflies are in york, pa now. I think that’s what killed one of my trees in Dover
