Where are treehoppers found?
Treehoppers are a predominantly tropical group, but many species are also found in temperate regions of North and South America, Australia, Africa, and Asia. Europe is an exception: only three treehopper species are known to occur there and one of these, the buffalo treehopper, was introduced accidentally from North America. Although treehoppers are quite common in temperate and tropical regions, most species are not collected frequently because they tend to be very patchily distributed and often occur high in the canopy of trees. The largest populations are often found on mature, isolated trees in meadows and savannas, possibly because populations of their predators and parasitoids are lower in such situations than in dense forests. Most species occur on trees for at least part of their life cycle. The species that are ant-attended are usually easy to spot because they often occur in dense aggregations that are surrounded by ants. Solitary species are often cryptic as both immatures a
