How to Manage Pests

Pests in Gardens and Landscapes

Buffalo treehopper—Stictocephala bisonia


Treehopper adults are commonly greenish to brown and 1/2 inch long or shorter. Covering the body, they have an expanded hood that may be formed into hornlike projections. Nymphs have numerous spines on the back of the abdomen, and both immatures and adults jump readily.


Treehoppers suck plant juices. This feeding damage is slight, although the honeydew they produce supports the growth of sooty mold, which may blacken leaves and stems when treehoppers become numerous. Treehopper nymphs are commonly seen in clusters on plant stems.


The buffalo treehopper is easy to control with a forceful spray of water. High populations of nymphs and adults may be reduced by spraying exposed insects with insecticidal soap.
