Thank you all for your kind comments.
Mulch, it was my lucky day, they are not so common but that day there were about 6 of them feeding of the same bush, and when they feed they hover for a few seconds. must have take 40 photos, but only 2 resulted in a decent image.
Ajopgotog, are you sure it is a male ? I read somewhere that the male's eyes touch each other, while in the female there is a gap. Would much appreciate it if you could confirm.
Richie, it's a canon 100mm macro. All phots handheld and using the onboard flash with a diffuser, as I cannot afford an off camera one.
Damage, nothing wrong with the hover fly, the legs are shaped so that they tuck into the body when in flight. For aerodynamic purposes I assume.
