Hi –
Found this guy in my garden this morning. Not sure if he is friend or foe. Hoping you can help!
Thank you for any insight.

Dear Ian,
This appears to be a Western Sculptured Pine Borer,
Chalcophora angulicollis, and according to BugGuide:  “Eggs are laid on bark of large branches or trunks of conifers, especially fir (Abies), or western yellow pine (Ponderosa Pine, Pinus ponderosa). Larvae hatch and cut through to inner bark, where they form tunnels.”  We are guessing you might have pine trees near your garden.  BugGuide also notes that adults feed on leaves, and we are guessing that refers to pine needles.

Hi Daniel,
Thank you very much for the information! What a great service you offer. All the best to you and BugGuide!
