Borers are insects (such as beetles or moths) which spend a portion of their development under the bark of certain trees. Many borers do not cause extensive damage to the tree and may only attack trees currently weakened by other activity. With that said, their are species of borers that can do extensive damage to healthy trees such as the Emerald Ash Borer or the bronze birch borer.
Adult clearwing Borers resemble wasp. The wounds from clearwing borers do not heal and invite fungi and other insects entry to the tree.
Usually, the Roundheaded Borer attacks dead or weakened trees. Heavy damage may occur from this pest which may cause the death of the tree.
