Thread subject: Diptera.info :: Dasyhelea as food in Crabronid larval chamber?

Upon cutting a dead Buddleja in my garden (Vienna, Austria), I found these breeding chambers in a twig - I assume these are Dayhelea or related Ceratopogonids.
And as the prey I suspect Crossocerus.

The eyes of Dasyhelea touch on top of the head. Some of these flies have smaller eyes more typical of Chironomidae.

Here is a close up - looks like the eyes are touching?
Also there might be several species serving as prey, also from various families - but the thoracic pattern looks very consistent in those specimens which are recognizable
