Possible Xylota sylvarum and Conops flavipes for id?

Hi Nick. Pictures are not showing. 

Sorry about the lack op photos - my first attempt to post - wil  try again!

Have had another go at attaching images!

The Conops certainly looks like flavipes. And the last photo looks OK for X. sylvarum (black distal half to hind tibia). The other three photos might be X. xanthocnema, but sylvarum sometimes has the black on the hind tibia obscured by golden hairs, so it's not always easy from photos. Wait for a second opinion from a more experienced hover nerd.
