Hi,

Are they definately hoverflies, as in the ones having similar markings to wasps?

 

Yes some look like flatter versions of wasps the others look like worker bee's

 

More likely to be mining bees than anything else. As such they are very useful and should not be discouraged. The holes will soon disappear. We have lots of them in our grass areas and they make little difference to it. Even mowing closely does not seem to bother them.
