After I saw a Spotted Lanternfly at High Mountain last week, I started giving unusual insects a second look.
Saw this guy near the house. I think I know what it is, and I wish I'd killed it (or at least tried to).
I post this in part as a warning to be on the lookout for strange bugs.
What is it, and why is it bad?
Diane Louie offered the correct answer: "It is a Locust Borer which feeds on Black Locust and can cause serious damage or death to the tree."
