The Buffalo Treehopper (Stictocephala bisonia) is a species of treehopper native to North America. It is also sometimes classified as Ceresa bisonia.[2]
Appearance
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.[1][3][4] It gets its name from the vague resemblance of its profile to that of an American Bison.[3] They grow to 6 to 8 millimeters (0.24 to 0.31 in) long and have transparent wings.[3][4]
Life cycle
S. bisonia mates during the summer months.[4] Males attract females with a song that, unlike similar songs used by cicada and crickets, are outside the sonic range audible to humans.[4] Females lay eggs from July to October using a blade-like ovipositor.[3][4] Up to a dozen eggs are laid in each slit made by the female.[3][4]
Nymphs emerge from the eggs the following May or June.[3][4] 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 non-woody plants.[3][4]
They molt several times in the following month and a half until they have reached adulthood.[4] At this time they return to the trees to continue their life cycle.[4]
Feeding
Both adult and immature Buffalo Treehoppers feed upon sap using specialized mouthparts suited for this purpose.[4] Black locust, clover, elm, goldenrod, and willow are among their favorite food sources.[4] It is also an occasional pest of fruit trees and is harmful to young orchard trees, especially apple trees.[4] It has become an invasive species in some parts of Europe.[2]
