When I went to my kitchen today I just found another male mayfly sitting close to this exuvia.
It flew away as I approached it, trying to get both, insect and exuvia on one pic.
I don't know if that was a nymph or a subimago. If it was a nymph I would be totally puzzled as the next small pond is more than 20 m away in my neighbours garden. Much more choices to moult between that and my kitchen window.
And please be tolerant about the cleanliness of my kitchen window.

We have a lot of pine pollen in the air right now. (damned sharp marco lens
