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