Thanks to Graham Montgomery for the tip about species name.
This was a new one for me. I had been looking for planthoppers for some time and concluded I was never going to see what is apparently a common insect. However, today was a lucky bug day for as I was photographing Enchenopa treehoppers I suddenly noticed this little critter resting on a twig. I thought it might be a tiny moth at first, but when it started to move I realized it was a planthopper! Great excitement. Great frustration too, because it was nearly impossible to photograph it. Eventually, after allowing me a few shots it dropped out of sight and I saw no more.
