Your letter to the bugman: We found dozens of these inside the house today. I think they got in when we opened doors, but we’re not sure. They are just under 1/2″ long, brown, and appear to have a 3 section body with wings.
How you want your letter signed: Is this carpenter ant, or something else?
This does appear to be a reproductive Carpenter Ant alate, and the wing veinage looks like that of this individual on BugGuide, so we believe you are correct. If you found them in your house, we believe they probably swarmed from inside rather than entering from the outside.
