Identifying the injury:
The first noticed sign of attack is usually a large number of small branches and twigs lying on the ground beneath the tree or dying branches and twigs hanging on the tree, nearly broken off. Close examination of the tree reveals branches with cut ends that have been chewed almost straight across as if cut with a knife. The injury will have slightly rounded edges and will feel a little rough from the beetles chewing on it.

Identifying the insect:
Adult beetles are about 1/2" long and grayish-brown in color, often blending in with the bark of a tree. Adults have long antennae that are as long or longer than the beetle itself. Larvae are as long or longer than the adults and are creamy white with a brown head.

Susceptible trees:
Twig girdlers can attack any hardwood but hickory, pecan, and persimmon trees are favorite hosts. Pecan groves and ornamental trees are often home to a large number of these beetles.
