Hornet - Dolichovespula maculata - female

Hornet - Dolichovespula maculata - Female
Elkton, Douglas County, Oregon, USA
May 8, 2009
After looking at the "info" on the guide, I'm guessing this is Dolichovespula maculata - Baldfaced Hornet, and because of its large size (each Hawthorn flower is 1/2 inch+), I'd say it's a queen. It also matches with the criteria, "Queens and workers may have lateral pale spots on the 3rd abdominal segment, and, rarely, isolated white spots on the 3rd tergite."

Moved from ID Request.

Right guess - Dolichovespula maculata
A spring queen nectaring on Hawthorn. No worker is on the wing by early May.
