Its not the drone fly is it?

That's the name of eristalis tenax.

The only reference I could get to pertinax being named the drone fly was a wikipedia article which didn't quote a source - now removed ;).

I note that naturespot uses the term 'tapered drone fly'.

Droning on...

The Eristalis seem to get lumped together as Drone flies, so it is appropriate for pertinax, too, I suppose.

Personally, Eristalis pertinax is enough. As for 'Tapered drone Fly', don't get me started....

E. tenax

Hi, I'm no expert but E. tenax has visible lines of hairs down the eyes. They are usually clearly visible but not always and that's a good ID guide as well.
