1317089 Asian longhorned beetle Anoplophora glabripennis Infestation in Chicago: before, during, and after cleanup. The only means of control available is to identify which trees are infested, cut them down, and chip them into tiny pieces. Such an approach can turn a tranquil neighborhood with tree-lined streets into a barren landscape

1627078 bronze birch borer Agrilus anxius This insect seeks out birch trees already in poor condition, then lays its eggs in bark crevices or near recent wounds.
1627077 flatheaded or metallic wood borer The adult beetles have hard shells with a metallic lustre. The heads of the larvae are expanded and flattened.
1626097 twig girdler Oncideres cingulata After laying an egg beneath the bark of a twig, the beetle chews a continuous notch around the twig which girdles it. The girdled twig soon drys out and breaks off; the larva develops inside the fallen twig on the ground. Damage to the host trees including elm, oak, hickory, dogwood, and others is generally insignificant.
1627073 locust borer Megacyllene robiniae Their larvae bore through the bark and tunnel extensively in the wood. Heavily infested trees may be so weakened that they break off in high winds.
1627059 snout beetles or weevils Half-moon shaped notches eaten into leaf edges are characteristic damage.

0007066 twig girdler Oncideres cingulata Pencil-sized twigs of pecan, hickory, elm, and other tree species are commonly girdled in the fall. It is not unusual to see branches on the ground under attacked trees or to see broken branch "flags" hanging from the crown.
0007067 twig girdler Oncideres cingulata By circling the branch many times, the adult female will cut the branch with a very neat and precise cut. The cuts are so unique that it is easy to tell when a twig girdler has visited the tree.
