Dear all,

This evening I made a picture of a mayfly or as we call them in Holland: one-day-fly. Unfortunately it was windy and so the delicate fly could barely hold on to my kitchendoor. And ofcourse there was not much light, so the picture is somewhat overlighted . I guess there is not much to say about this specie. I am just curious whether the yellows balls are it's eyes.

These mayflies fascinate me. I seldom see them, but that is not so strange, because they do not live that long. It is a good thing that I took a picture

a picture from the right angle, I think

Hi Shar.
I think that your Ephemeroptera is male of Cloeon dipterum.
It is one of the most common Ephemeroptera. Larvae of Cloeon dipterum live in small ponds even with dirty water.

Dear Nikita,

I think you are right, thank you

Hello Shar,

Males in some Ephemeroptera sp. have so-called turban eyes.
The upper part (the yellow ball in your picture) with bigger facets is clearly separated from the lower (dark) part.
