These long-horned beetles have a nickname - twig girdler, for a very specific reason. In the late summer and fall, they become very busy on a variety of trees, including but not limited to: pecan, hickory, persimmon, and elm.
The best way to control these is to clean up the fallen limbs and dispose. The adult beetle cuts the branch and lays eggs on the fallen limb, the larvae overwinter in the dead branch, and the next generation emerges in Mid August or so. Only one generation occurs each year, so by sanitation practices, the life cycle is broken and numbers are reduced.
