Hi, can somebody identify this larva? The picture was photographed in May. Thank you, Marion. Marion Friedrich attached the following image:  [94.6Kb] Edited by Marion Friedrich on 07-11-2010 11:51 |

Hello Marion, I consulted the book of Rotheray, Graham Colour guide to Hoverfly Larvae by published by Derek Whiteley, Sheffield, 1993, and I have two indices : 1°) Syrphus ribesii or 2°) Parasyrphus nigritarsis http://www.hoverfly.org.uk/viewtopic.php?t=10&start=0&postdays=0&postorder=asc&highlight= what would be good to have a closeup of the face of larva and a view from above ! Best wishes Pierre PIERRE http://cyrille.du...orange.fr/ http://www.hoverf...portal.php |

Hello Pierre and Paul, thank you very much. I attach the other existing photos for decision. Unfortunately focus depth was too low. From the face I have only a side view. Best regards, Marion Marion Friedrich attached the following image:  [115.63Kb] |

Hello Pierre, I do not have access to the book you mentioned, but I think you are right. Syrphus ribesii and vitripennis are very common in my region. Parasyrphus nigritarsis should also exist, but seems to be uncommon. Amongst my photos I could not find any picture of an adult P. nigritarsis, but a lot of S. ribesii. I also found some pictures quite similar to my larva in internet: http://www.rutkies.de/Syrphidae/artikel/index.html This larva was raised and confirmed as S. ribesii. Thanks for ID. Greetings, Marion |
