Definitely Stratiomyd larva, but I cannot tell which genus. For that I need a detailed photo of the anal segment in dorsal or/ventral view. The anal segment appears to have only single hairs (so no Beris). On the photo bottomright, I think I can see that the antenna is placed somewhat mid-dorsally which I think fits best with a member of a Pachygastrinae. But detailed info on the position of the hairs on the head and anal segment is necessary.

Based on the lateral view in the bottom left image I would say it had already pupated...
