Where Photographed
Hi Mason-

Where in King County was this mayfly photographed? I'm struggling a bit with this. Was it from the same location as the other one?

Yup, same spot, different date. This is a spot I just refer to as "The Pillar", it's a large pillar at the front of my house with a light on it. It gets plenty of stuff randomly throughout the day (like the other mayfly), as well as stuff attracted to the light at night (like this mayfly). It's netted me well over 200 different species of arthropod over the past year.

Running or still water?
I assume your house must be in close proximity to a stream or lake. Which is it?

My house is not to far from Lewis Creek, which is running, but also has a large Still water marsh area. I'd say the running part is a good bit closer, though both are within a mile.

Hi Mason-

I believe this male imago to also be of (family) Leptophlebiidae, and either of (genus) Paraleptophlebia, or of (genus) Neoleptophlebia, into which three former WA Paraleptophlebia species were re-classified several years ago.
