Baetis Muticus ili Baetis Niger?

Prekjuče na Gradcu se sporadično rojila poneka jednodnevka, nekako uhvatih jednu i baš me iznenadila!!! Iako sam bio
uveren da je to Baetis Rhodani ova jednodnevkica je bila upadljivo manja, sjajno tamno braon tela i izrazito tamnih krila...
Dva repića i skriveni par krila ukazuju na rod Baetis, a veličina i boja ili na Baetis Niger ili na Baetis Muticus (što je moj favorit).
Ono što je zanimljivo je da po našim sajtovima nisam našao prisustvo nijedne od ove dve vrste u našim vodama...

Kako Vam se čini na osnovu ovih loših fotki???

Evo još jedne fotke na normalnom svetlu, koja ne blješti na suncu...

That hind wing looks to be large for a species of Beatis.

If it had three tails it could possibly be Habrophlebia fusca - the Ditch Dun.

It had only two tails Ray (not so obvious on the photo but I saw it very well), and was a pretty small one - about 5-6 mm.

With only two tails I am not sure what it is.

But I still think the hindwing - especially in the second image, looks a bit large for the species of Beatis I'm familiar with in the UK.

Well - thanks for help Ray!
Everything (area, temperature, time, place,...) inducing that the fly should be some stunded extreme dark B.Rhodani but simply I dont think so...

If pictures were better - maybe we could make some better conclusions. With these photos we can only speculate...
