Hi Richard - is that a bit of jam to attract the wasp?
It's nice and bright but you have to nail the focus on the head/main part of the body. There's probably around 5mm depth of focus to play with by the looks of it - so it's just a case of taking 5/10 shots with slight movements of the focus ring or using any focussing aids that your camera has.

Hi keef - not a bad shot really apart from the focus - what lens did you use?
How are you focusing? With the focus fixed and moving the camera, or using the focus ring, or using autofocus?
Have you tried that setup with a test subject? Doesn't matter what - just something that doesn't move. Can you get good focus on a test subject?
