Hello,
this 7-8mm larvae is from two days ago from the pith of an old Cirsium arvense stem near Cologne.
I'm not even sure whether it's a diptera larvae. Is it? Perhaps Tephritidae?
Thanks,
Michael

Not Tephritidae surely, if the substratum was decayed it may be some Sciara (in case it is Diptera).

Thank you for your answer,
the substrate was indeed decaying. The thistle was from last summer and has been dead for 2 or 3 month, and got some heavy frost in january. The larvae were found in the humid base of the stem.
