Many thanks, everyone! Appreciate you taking the time to comment!
"Deliberately" clipped the wing, Charlotte, as I wanted a closer shot than can be fitted into viewfinder (and I rarely crop into a shot - don't like to waste pixels!

Yeah, always fighting for more DOF, Dan! Would be nice if Sigma could bring out a stabilised macro - those extra 2 stops would make all the difference
