Wasps and hoverflies

During the summer I saw two Volucella species (inanis and zonaria) feedind on umbellifers about 8 meters from a wasp nest in a log over several weeks.  The wasp nest became quiet ( i.e. no wasps) unseasonably early during August. Other nests are evidently still active judging by the number of wasps I see every day.  Is it possible that the hoverflies wrought such destruction on the wasp larvae that the wasps in that particular nest gave up?

I could of course invade the log and see what's in there but I am reluctant to do that in case there are Volucella larvae in there. Not very scientific but there you go.
