I found 8 ant queens(?) today near Mosier, Oregon, which is generally considered the border between central Oregon and Western Oregon. I found them on a dry slope with some sand and dirt and almost no (alive) vegetation, today, april 3rd. 6 have the orange head while the other 3 have a black head, I assume they're different species. Pictures with and without measurements ->
Never gone looking for ants before, so fingers crossed they are actually queens, thanks for the help!
