Thanks for the comments Astro-Bot, Rowland, Rick, Jeanette, Geoff, Ken, Mark and Andrew, I appreciate them.
My wife originally spotted this guy and when I went to have a look, the wasp took off and hovered around me before heading off, I assume that I was not considered a threat.
A few minutes after the wasp returned, I grabbed a few shots with the 7D and 100mm F2.8 macro lens and the wasp didn’t seem to mind the attention. I then set up the tripod with the 5D and MPE-65 when the nest was empty and once again, this did not appear to affect the behaviour of the insect upon its return.
It was fascinating watching the behaviour through the viewfinder and when my diffuser clumsily brushed the foliage, the wasp took off and circled me and the gear, but I didn’t feel threatened and soon the insect settled down again.
It has been quite an experience having this close up insight into the industrious behaviour of this amazing insect.
@Mark; Thanks for that very interesting information. We are currently having the house re-roofed, so the scaffolding, materials and on-site work have prevented me from accessing that corner of the garden – I hope that the wasp will still be there after the work has been completed.
Cheers
Dennis
