bees or wasps
I found these bees (or are they wasps?) on a tree root in our yard in central North Carolina. It looks like they’re burrowing into the wood, but they don’t look like carpenter bees to me. I have seen up to 4 at a time with their heads partly in the root. I also think I can see one inside the burrow. Any ideas?
Giant Hornets, Vespa crabro germana, were introduced to this country in the mid 1800s. They are gathering wood pulp for their large paper nest.
