dead tachinid larvae? or pupae?

Hello
I'm new to the forum so apologies if this is posted in the wrong place!
I've attached a picture of an unfortunate caterpillar that had 4 tachinids emerge from it! I initially thought these were two separate species. But the only photos that I've found of tachinid pupae on the web look like the dark one.
So now I fear that in moving the container from a caterpillar-friendly environment to a supposedly tachinid-friendly one, that the three are actually larvae that have been stressed by the move and died.
I would be very grateful for any information... especially if it is that they could be two species ;-)
thanks
Annabel

I think your idea is right.  In the photograph there is definitely one fully formed puparium and the other three look like larvae that have not got as far as complete pupa formation.  I would, however, suggest you post this photo on the Tachinid Recoding Scheme website for the opinion of the Tachinid family experts:
