Hi, can somebody identify this larva? The picture was photographed in May.
Thank you, Marion.

Syrphid larva...

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

what would be good to have a closeup of the face of larva and a view from above !

Best wishes

Pierre

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

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:

This larva was raised and confirmed as S. ribesii.
Thanks for ID.

Greetings,
Marion
