found the shell of this insect on a Red Maple in North East Pennsylvania the other day. It seemed to either attach itself to the tree or was feeding through the bark. Some more observations: the Red Maple is in a large office complex parking lot, it is a stressed tree with what looks to be a history of abiotic damage looks like mechanical as well as bark splitting from freezing and thawing. Crown also had been damaged at one time. So thinking the insect is there because the tree is already weak from stress, but I don’t have a clue as to what it is... oh also the soil conditions as expected are terrible.... surprise surprise
