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. greeting Robert Robert Heemskerk attached the following image:  [189.85Kb] Edited by Robert Heemskerk on 16-07-2021 22:14 Greeting, Robert Heemskerk ---- WWW: http://robertheem...ndedag.htm --- |

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.
