Interesting that the wings stick so well to your finger, I often see mayflies similar to this somehow adhered to clean glass by their wings, I don't even know how. Many are still alive when stuck.

He was found (Deceased) in the pool. This photo was taken right after he was removed from it. The wings might stick because they are extremely flimsy and delicate; his wings broke upon collection. Also, they don’t have much flight power. If there was any moisture on that glass, they’d be stuck to it like glue.

Tricorythodes explicatus
Hi BugIdentifier-

I believe this male imago to be Tricorythodes explicatus.

The why is because mayfly male imagoes characteristically fall to the water and expire following their in-flight mating. Whereas, mayfly female imagoes typically don't expire until dropping (or depositing) their eggs on the water surface. The eggs sink and stick to the substrate, where they typically mature for several weeks.

Once mature, the nymphs break out if their respective eggs, begin feeding and growing until the are mature and ready to emerge and depart their aquatic environment, as a subimago.

Subimagoes, once on the water's surface, having escaped from their external skeleton, and having pumped fluid into their wings, they take flight to streamside vegetation. Mayfly subimagoes typically rest in the shade for a day or two, until they are ready to undergo the subsequent metamorphosis, which turns then into sexually mature imagoes. Then, they take flight once again to form or join a mating flight.

Thanks so much!
