Diplazon species
One of the most common parasitic wasps in Europe is Diplazon laetatorius. The eggs are laid in the pupae of various hover flies, especially species belonging to the Tenax-group (Drone Flies). Even though it is very common, it is not often seen by people. When you do spot it, look at it carefully, because it is a beautiful animal indeed! The animal depicted here is likely to be a Diplazon species, but probably not Diplazon laetatorius.
