My dad found an interesting beetle and I was wondering what type it is exactly. So far I’ve figured out it’s a longhorn beetle, but not much else. I’ve found many similar looking beetles, but not with the exact coloring. Most I’ve found are black with yellow markings, but this one is reversed. Do these types of beetles damage trees? We like beneficial insects, but our trees and plants are struggling and we don’t want to keep harmful insects around.
You are correct that this is a Longhorned Borer Beetle in the family Cerambycidae. We will attempt to identify the species for you. Though the larvae of Longicorns bore into wood, very few are actually problematic. Most Longicorns are very host specific.
