WAnimals has 3 species of cicada, spread across 3 families (Cicadellidae, Cicadidae, Fulgoridae).
Ranges calculated from the profiles that record the figure, not from all 3.

Its body is coated in brochosomes, microscopic protein particles that it secretes and spreads with its legs, forming a water-repellent layer that sheds both water and its own honeydew.
From
It jumps by driving off with its hind legs at accelerations of several hundred times gravity.
From
Detected in Pennsylvania in 2014, it has become one of the most publicised insect invasions in the United States, with campaigns urging the public to squash any individual they see.
