A couple of bugs
 
Found this one on my door a few days ago. I'm stumped on this one. Anyone?

A Hex.

this is a long shot but some sort of Mayfly?

The first couple are of a male, spinner (imago) in the Stenacron (Light Cahill) family... not sure of the exact species.

The second set is interesting... also a male, imago... looks like it may be a species of Isonychia - Slate Drake (perhaps a warmwater species?).

What rivers/streams are close to your house?

These are both likely from the Ohio River. I'm absolutely certain the second bug is a Hex, they were hatching at the time the photo and even made the local news. I've seen these plenty of times and are becoming more common on the Ohio.

The first one throws me. I was thinking Cahill, but the ones I've seen have been more creamy yellow in color in thorax and abdomen.

One commonality is that I found them both roughly around the same time of day (7:00-7:30pm), though weeks apart in appearance and nearly the same location.

My first stop is usually troutnut.com but the site seems to be down. Hopefully this is only temporary, that's an incredible reference to have access to.

I think the first one is definitely a Cahill; the second by looks is a Hex, would be easier to tell if you had something to show actual size.

Post your question to the Entomology forum here and I'm sure the moderator of that section, Taxon, will be able to identify it... Fly Fishing Entomology | Washington Fly Fishing

Yes, lack of size comparison makes it a little tough. I didn't think the wings looks massive enough to be a Hex, but the overall coloration certainly suggests Hexagenia.

Really? I would never have guessed hebe. I thought those dark spots on the forewings are a diagnostic field mark of the classic "summer" Cahills.
