Ash Bark Beetles in sick ash trees


Above: An example of ash bark beetle damage.

Another group of insects that can be found boring into dying ash are the ash bark beetles (Hylesinus). There are at least two species in South Dakota, the eastern ash bark beetle (H. aculeatus) and the western ash bark beetle (H. californicus). These insects create a round exit hole 1/16-inch diameter, about the size of a BB, and often these holes will encircle a shoot. The galleries beneath the bark consist of a main tunnel with numerous smaller tunnels run off from it and following the wood grain.
