On small Yellow Box (coppice regrowth). Many adults (mostly paired) and nymphs on same tree and another nearby. Closest photographic match I have found on the web is Eurymelops rubrovittata, but this seems to be a different species. Host trees will probably be slashed by Parks Victoria soon as in previous two years.
Update: I have added another photo which shows the markings on what I assume to be the female. Since these match other photos on the web (including museum specimens on ala) I have changed the species to Eurymelops rubrovittata.
A very confusing photo of some stem galls on a young (about 1m high) Yellow Box, one branch of which was almost completely covered in galls. The red is obviously a gall, but the green blades that look like leaves are parts of another type of gall. Of course there are the usual attending ants, but then if you look closer there are orange dots which are perhaps eggs of some kind, and what look like early stage Hemiptera nymphs. Are these nymphs associated with the gall in same way, and if so how? If they are a gall forming species shouldn't they emerge as adults? Wish I had the equipment to be able to watch what is going on for a few days.
