Looks like a Tisza mayfly
I googled Tisza mayfly and the images i see are very similar but my picture was taken in the US. My apologies I should have mentioned that in the original post. Also this mayfly isn't that large, maybe an inch/2.5cm
This one is fresh from a molt. I've seen them teeny tiny.
Maccaffertium modestum would be my guess based off of similar images
