I think I saw around four of the small nymphs jumping in the area. This one posed nicely for me, so I could get photos of it. The resolution wasn't great because it was so small.
C. baldersoni appears to be the only species of Chlorodectes found on the eastern ranges and south coast of NSW according to Rentz & Su. The late John Balderson was a research office in Orthoptera at ANIC for many years amd worked under Ken Key and Dave Rentz.
