Hi, thanks all for your help so far, i've a few more that i'll try and post over the next day or so and get clearer images of those that people have requested.

Does anybody have a clue what this species/genus this fly is? Taken on the 21st May last year at Powerstock Common, Dorset in a mixed woodland/meadow habitat - seemed to be sitting on a Common Spotted orchid. It was ~10 mm.

It's an Asilid, but the abdominal pattern does not ring a bell. Should be very distinctive ....
You don't have Cyrtopogon, do you ?

If you don't have Cyrtopogon, it must be that
