Forest Leafhoppers
Forests probably harbor more leafhopper species than any other ecosystem, and most of the species that remain unknown to science probably occur in the canopies of tropical rainforests. Recent sampling of Amazonian rainforest canopies by entomologists at the Smithsonian suggests that 80% or more of canopy leafhopper species are undescribed.
Common forest leafhoppers in North America include the deltocephaline
genus Scaphoideus, some species of which have been shown to transmit
tree diseases such as elm- and ash-yellows, and Erythroneura, which,
with over 800 described species worldwide, is one of the largest of all
leafhopper genera.
