Norway, 01.05.11.

I have no idea where to start with this one. Fist time I really looked at a mayfly.
About 10mm excluding tails (of which there were two).

Hopefully someone can help me to get genus or maybe even species.

Ephemeroptera, and it must be genus Epeorus, for it is the only one I know of, whom has two tails

The wing looks very like Leptophlebia marginata, so I think you lost a tail filament - there should be three!

Baetidae, Heptageniidae (including Epeorus) and Siphlonuridae all have only two tails - but this wing is not from any of them.

Tony,
of course you are absolutely right. I looked in Bauernfeind & Humpesch (2001) and indeed many more genera (in the adult stage) have two tails. and the wings look indeed like a Leptophlebiidae. I made a mistake with the nymphal characteristics: the nymph of Epeorus is the only genus with 2 filaments.

Thankfully not all children look like their parents! :D

Leptophlebia marginata is correct, a female imago
