I had hoped that this would not be the invasive harlequin, but a little bit of research tells me that it is. The small triangular white patch at the front of his head is the giveaway.
@stimuloog@davidlostphojo here is the problem - they are an invasive import - they are cannibals - and they spread sexually transmitted diseases. So not a friend to our native species.
Is there a natural predator you can introduce to get rid of them? This seems to be the practice now and when the food source dies out so do the predators. Well, in spite of him being a "bad bug" the shot is really good!
