Hardwood Borers-Wood borers found in hardwoods in this region usually attack trees that are experiencing some form of stress, with the exception of clearwing moths (Sesiidae), which attack apparently healthy trees. Borers found in
hardwoods are problematic because they can be one of the factors leading to tree
decline or death. Wood borers may attack hardwoods year after year, and attacks
may eventually cause branch death or create a weak point in the tree that is prone
to wind breakage. Some hardwood borers like the cottonwood borer develop in
roots and can cause severe damage to young trees. Wood borers found in hardwoods can be beetles, moths, or a single wasp species
