This species is native to North America, but now it is widespread throughout southern Europe and it is also present in the Near East and in North Africa.3
Buffalo treehoppers are a bright green color and have a somewhat triangular shape that helps camouflage them so as to resemble thorns or a twiggy protuberance.456 It gets its name from the vague resemblance of its profile to that of an American bison.7 They grow to 6 to 8 millimeters (0.24 to 0.31 in) long and have transparent wings.89
S. bisonia mates during the summer months.10 Males attract females with a song that, unlike similar songs used by cicada and crickets, is perceived by the female not as sound waves but as vibrations through the host plant.11 Females lay eggs from July to October using a blade-like ovipositor.1213 Up to a dozen eggs are laid in each slit made by the female.1415
Nymphs emerge from the eggs the following May or June.1617 The nymphs, which resemble wingless adults, but have a more spiny appearance, descend from the trees where they hatched to feed on grasses, weeds, and other nonwoody plants.1819
They molt several times in the following month and a half until they have reached adulthood.20 Then they return to the trees to continue their life cycle.21
Both adult and immature buffalo treehoppers feed upon sap using specialized mouthparts suited for this purpose.22 Black locust, clover, elm, goldenrod, and willow are among their favorite food sources.23 It is also an occasional pest of fruit trees and is harmful to young orchard trees, especially apple trees.24 It has become an invasive species in some parts of Europe.25
