 Is this a Dasysyrphus larva?

This is my first post, so apologies if it doesn't go quite right - for a start I can't work out if I have inserted an image or not! I'm a member of the iSpot website in the UK and have got interested in trying to identify obscure larvae that no one else has tackled. This is not my photo; it was taken in October 2016 by Paul Roughley in mid-Wales, near Welshpool. I don't have any info about size or habitat other than that. The original observation is at https://www.ispot...ly-species Having looked at images on this site it looks to me to have the overall characteristics of a Dasysyrphus larva, but I can't find a species that matches, and the image looks kind of odd (so much so that someone has suggested it might be plastic!). Any help gratefully received. |

Cannot help with ID, but with the image URL, you can just embed it in a forum thread - here is your observation:
Cheers, Lorin Font Color All requests are from the urban area of Vienna, if not otherwise stated. My Diptera observations (and other living forms) can be found here, and corrections or comments over there would also be appreciated. |

Hi Sarah, I'm sure, it's a Syrphidae larva and it looks like Dasysyrphus. But even to confirm the genus it would be necessary to see the posterior end of the larva which would not only show the spiracles but also 2 long tapering projections. I could not find a similar Dasysyrphus. Greetings, Eric Edited by eklans on 14-03-2021 09:45 |

Thanks so much Eric, greatly appreciated. That is really worth knowing for my own observations too. I will stick to Syrphidae for this one in that case. |

Yes Sarah, for larvae of Syrphids the posterior view (dorsally and laterally close) is extremly important. Maybe Paul Roughley will find one again in Y Trallwg this October. Greetings, Eric |
