Syrphidae. Eristalinae. Probably Eristalis. Have a look at http://www.canaco...stalis.htm You may find a match among these. Tony ---------- Tony Irwin |

Indeed Eristalis, one of the northern species which can be found in the Palearctic as well as in the Nearctic. This looks like a female Eristalis fratercula, but from a picture it is not a 100% ID. Greetings Greetings, Gerard Pennards |

Thanks for the reply on my ID request. Any idea if the larva might be aquatic/semiaquatic? John |

Hello John, It seems to me that the larva of Eristalis hoverflies of the genus are aquatic, feeding on decaying matter. The specialist opinion is preferable  Best wishes Pierre PIERRE http://cyrille.du...orange.fr/ http://www.hoverf...portal.php |
