Mmmmm ...... thanks all. Not sure.
I'm guessing that they are not Horse Flies - don't look big enough. Thank goodness.
Dung flies - possibly. Look more brown than yellow though.
Not blow flies because not green and not buzzy.
You don't mean Plums that you actually try to wash off that wonderful sheepie aroma. How about sheepie smelling soap. Lovely.
Bionic - not wierd at all.
Will have to put spinning on my list of things to do.
