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. Live specimen here: http://www.flickr...otostream/ cyprinoid attached the following image:  [119.95Kb] Hyperbolizer |

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!

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. Edited by atylotus on 03-05-2011 10:17 |

Thankfully not all children look like their parents!

Leptophlebia marginata is correct, a female imago |
