Boring Insects

Boring insects can cause a lot of damage to your trees and can often kill them. There are many types of insects that fall under the boring category. They generally attack weakened trees that are damaged or malnourished. Ultimately, if not treated swiftly, the tree will die.

Boring insects include beetles, moths and wasps. These are the most common boring insects in Texas.

  1. Red-headed ash borer (Neoclytus acuminatus) is one of the most common tree-boring beetles in our area. Its narrow, reddish body is covered with yellow lines on the wings. They feed on many species of trees including ash, oak, elm and even grape vines. You’ll often find adults in deadwood or your firewood pile.
  2. Red oak borer (Enaphalodes rufulus) is known for attacking oak and maple tree. The adult beetles are reddish brown and lay eggs in the bark crevices. July and August are their busiest egg-laying times. The larvae then tunnel under the bark and into the tree.  These destructive larvae can feed for an entire year and can cause serious girdling and branch death.
  3. Cottonwood borer (Plectrodera scalator) is frequently found on cottonwood and willow trees. Adult beetles are black and white and are active from about May through August. The larvae actually tunnel into the tree at the base of the trunk, often below the soil level and can feed on your tree for about two years.
  4. Locust borer (Megacyllene robiniae) are dark brown beetles with yellow markings. Like other beetles, they lay their eggs between the bark and then the larvae tunnel into the tree. If you see wet spots and frass on the bark of your locust tree, you probably have borers. Larvae hatch from eggs laid in bark crevices.
