Yeah, the introduced wasp species are very nasty. They’re an extinction-machine for a lot of our native invertebrates, and incredibly hard to control at an ecological scale.
This is the Springbok one
Setup was the standard camera, macro lens and ring flash. I also set up a blue card behind the insect, with the aim of bouncing some light back on to her (and banishing the black areas that often are produced by the small apertures of macro photography). You don’t always have scope to use a card with macro photography, but its a good cheap tool when you can.
Of course, picking a still day also helps; even light wind will produce too much motion to track the insect.
They’re an alert insect, and often turn to look at the you. I’m afraid she always looks like this, it’s not post-coital
