Geographic location of the bug: Bellingham washington

I was outside just as it was getting dark and I heard a weird bug flying around. Well it was a big something and then I notice a few more over by the house. It’s fall time here and nights get down to the 40’s.
I am sending a phone I took please feel free to use it.

These are Predaceous Diving Beetles in the family Dytiscidae, but it is going to take someone with more expertise in the family to provide you with a species identification. Though they are primarily aquatic, as you observed, they are capable of flight. According to BugGuide: “Adults with long hairs on hind tibiae and other modifications for swimming; move their hind legs together like oars, like Backswimmers do.”
