How many species of leafhoppers are there?
No one knows for sure. Approximately 20,000 species have been described (making Cicadellidae one of the 10 largest families of insects), but many new species are being discovered each year. Based on preliminary samples from Amazonian rainforest canopies, the true number of leafhopper species may exceed 100,000! New leafhopper species are being discovered almost every day; click here to see a list of the most recently discovered species.
