On the side of a tree at the Arboretum's Southern Tablelands Ecosystem Park there was a small white egg sac with a tiny parasitic wasp on the surface, as seen in the first image. The wasp was around 2mm in length and was seen gradually working its way around the egg sac searching for prey. The prey might have been the tiny orange coloured insects that can be seen around the periphery of the egg sac and in the final image. They appeared to very small versions of tree/plant hoppers.
