First I observed this yellow ichneumonoid to search for or inject into something in the flower head for about 15 minutes.
Then, a Chalcidoid wasp (Eurytoma?) joined.
Can the ichno be further IDed, also interested in the possible host - I know several tephritids develop in Centaurea

Vienna, mid August

Not sure, but the yellow parasitoid looks like a braconid (close to Bracon?).

I took the flower head with me and opened it:
looks like the wasp was targeting a tephritid larva
