Unsure what this is so I initially placed it under 'Beetles.' It now appears that it might be a Thrip. It was sighted on the side of a Eucalypt, adjacent to a Hopper, as seen in the final image. There was no interaction between the two insects.
Hi Tim You could try "All Thrips (Thysanoptera) sightings" There's no obvious matching one there, but it's worth a try - I hope you can solve this one.
