Thanks Cam, Laurie, Carlos and Ken, I appreciate your comments.
For stability, I used a broom pole in my left hand and by relaxing my grip, I can slide the macro rig up and down the pole. When I am at the right level, I then tighten my grip which steadies the camera and lens combo. It’s then just a matter of slowly swaying in or out until the insect is in sharp focus in the viewfinder, then hoping that the shot is in focus!
Cheers
Dennis
