That's the bugger, Wayland!
If that one's the Robber Fly, then the one I'm describing as being local to me must be the Mugger Fly!
I'm astonished at the variation within the species. If only Darwin had studied Clegs, he could have saved himself a helluva bother!
What an incredibly informative thread this has turned into, which has answered a lot of questions I've asked myself for years -without having taken too much trouble to answer.
Brilliant photos all, and the last is just the way I like to see them.
