From a friend I got a box with a dead Aeshna isoceles in it.
This afternoon I discoverd soms larvae in the box and some pupae.

These are Phoridae I think?

What is the relation with the dragonfly?

Also in the box I found 3 little dead ants, this could also a possible explination for these Phoridae larvae?

I like to know if there is a relation between these.

Disney (1994) mentions 34 species of phorids known to bred in dead insects, with Megaselia rufipes and M. scalaris being the most frequently cited. I don't think the phorids are parasites of the dragonfly - just very efficient scavengers.

Yes, especially as it's a female. If you have a male, it may well be possible to put a name on it, but it will probably need to be slide-mounted to be able to see all the necessary bits.
