Mayfly

Captured on a vertical rock over a narrow artificial wooden path over the water. I think I have just identified it! Hope it is correct!

Glad you found the ID, Jivko. In dutch we call this order "one day flies", referring to their short life span. Looks like you witnessed the few hours or days of its adulthood. Posted 8 years ago

Hi Jivko,
It's not Ephemera danica. From the species I know (northwest European) it would be (a female) Ephemera vulgata.
According to FE Bulgaria has no other species than the ones known to me, but Ephemera hellenica, zettana and maybe parnassiana occur closely enough nearby to maybe be found in Bulgaria one day (??) and I have no good idea of the IDing characters and variability of these :-/
Some other Ephemera on JD are misidentified too I think, so I'll have look, but these are not my speciality.
For the species occuring in Bulgaria there are some excellent collages here, that will help in IDing - look closely at the patterns on the dorsum:

Ephemera glaucops is another one occurring nearby and you'll find some images/info here:

Scroll down on that page to find this image that may help a lot too :
