From midwest Sweden 2006-05-26. Can anyone ID this? First I thought Ephemeroptera, but their second wing pair is either really small or missing. Don't look like Odonata either ... Is it some kind of nymph stage? I'm lost

I will not hazard a guess to the species, but it is an adult with four fully developed wings. The hind wings are significantly smaller than the fore wings, though.

Hind wings are absent or very small with 3 or less longitudinal veins in Baetidae and Caenidae. |

According to Lars-?ke Janzon (NRM) it's a Ephemera vulgata (Ephemeroptera::Ephemeridae). |

Wow - it's the strangest E.vulgata I ever saw then  All the ones I see here in England have mottled wings and a much paler colour on the body. What kind of river was it found near? Slow and muddy or fast with stones? Edited by ChrisR on 15-09-2006 10:10 |

Slow and muddy or fast with stones? Hi Chris! Well, I've seen a few photos on the web all with rather light colored species. Perhaps the animals get darker when older, but what do I know ... It was found near a small stream with slowly running water both muddy and sandy with stones, but not much water. That place is about 1,5 km from lake V?nern (Swedens largest lake). |

Hmm, OK. I am no expert on Ephemerotera but I do come across Ephemera lineata, vulgata and danica quite frequently here. A friend of mine once said that danica were always found in fast-flowing rivers, while lineata and vulgata tended to be in slower, muddy rivers - and I have found that to be the case in England certainly. |
