I found this bug in my yard and found out it is a locust borer similar to the hickory borer but we do not have the trees i read that it lays its eggs in. I have all kinds of trees around us. but none like it said this thing likes. We are in the inland pacific northwest and even your report says they are not native to here. how do we protect our trees from them?

Dear worried about this bug,
As you letter indicates, the Locust Borer, Megacyllene robiniae, is native to the eastern portions of North America, however, with the cultivation of its larval food plant, the black locust, as well as the more decorative locust cultivars, the range of the Locust Borer has expanded to the Pacific Northwest. The BugGuide data map shows states that include sightings submitted to that website. You do not need to worry about other trees as the Locust Borer is host specific to Locust trees.
