Casey - I would assume they are. It would be odd to have two different species inhabiting the same object.  Tom Parker  On May 17, 2023, at 11:59 AM, 'Oehler, Casey L' via MuseumPests <pestlist@googlegroups.com> wrote:  Thanks Tom and Stephan! Tom, I just wanted to confirm that in the scenario above the active green larvae and adult wraps we found are the same species? Thanks again for your insights!

Fresh holes are the color of newly-sawn wood.  In time, the holes age and become dark.  You are picturing dark, old holes. Then a variety of wasps take advantage of these holes and use the galleries in which to raise their young.  They usually provision the galleries with paralyzed insects on which the larvae will feed until maturity.  When the adult wasp emerges, it flies from the hole, finds a mate, and the entire cycle begins again. A common practice to prevent continuing infestation and possible rot from rainwater entering the holes, is to seal the holes with colored wax.  Wax pencils in varying colors are available from any well-stocked hardware store.

We are looking for help identifying a wood boring insect found in an outdoor post in Southeast Alaska. We are waiting on wood identification of the post. Attached are pictures of the larvae, adults, and damage.
