A male Hydrophoria. In Britain this would key to H. linogrisea. The yellow postpedicel and genital segments and the lack of darkening on the fore-femur seem unusual compared with the few images I have seen,but they may well be within normal variation. (I see Fauna Eur. lists an Asian species H. rufitibia which has appeared in Germany and Greece, but I know nothing about it.) |

Now I've found Suwa's 2002 paper http://eprints.li...09-127.pdf in which he retracts the identification of the German H. bavarica with the Japanese H rufitibia. It's probably irrelevant anyway. The paper makes little mention of colour, and you can't know anything without a good view of the genitalia, but one characteristic of the group is the shortness of the ad seta on t1 compared with the neighbouring setulae - not the case here, so probably H. linogrisea is correct. Michael?

1av on hindtibia and sternite V / hypogygium seems orange/yellow, so maybe Eutrichota praepotens.... |

It's clearly E. praepotens - only an idiot would think otherwise.  Still, public embarrassment is very character-forming  |
