Olga,
I had seen Ledromorpha planirostris before I just didn't remember where. So I dug around the Internet for a while until I found it's picture along with the scientific name. I came across the scientific name several times with no pictures but I finally found the picture and the name together. It being the largest leafhopper in Australia means L. planirostris is commonly referenced. Not to mention the interesting history behind the person, Donovan, that discovered the species in regards to drawings of a male example of the species that never existed. Kind of a entomological soap opera...
As far as getting out more is concerned, you are never going to see every species you think you should see and you won't always know all the species you think you should....there are just too many!!
