Hoverfly

I took 23 shots to get this almost in focus hoverfly flitting around the rosebuds. With 280 species in Britain to choose from I wouldn't like to name it precisely, but it does look  very like the photo of a marmalade hoverfly at NatureSpot. It's a great name so I'll call it that if I see it again.
