Hi everybody,

I found this larva on what I think was Lactusa virosa. I kept it and got an adult but the ID is still doubtful so perhaps someone familiar with larvae could help to clarify this.

So what would be your best guess for it?

Thanks in advance!

Hi Cédric, I think it's a Syrphus ribesii, red colour form - the first image shows that the prp is about as long as broad and the spiracular openings extend over the sides of the prp.

Thank you Eric!
Based on the imago, we hesitated between Syrphus torvus and perhaps some Parasyrphus.

I will have a look to the guide you mention, thank you!

Based on the imago obtained from this larva, this is Syrphus torvus.

Hello Cédric, I've compared your fly to my S. torvus which I found 2017-04-11 and the eyes look the same! So I'm quite sure it is S. torvus. Which means, that the larvae are very similar, too - which could be expected, I think.
