    Two-Marked Treehopper - (Enchenopa binotata)

    Small but mighty, the Two-Marked Treehopper is an able jumper and flier moving from branch to branch on trees and plants.

    Staff Writer (7/21/2017): Treehoppers are a plant-sucking insect that has the ability to leap far and fast. This is a fantastic escape maneuver when threatened by a predator. The movement is so quick, it is often impossible to tell which direction it went. Two-Marked Treehoppers are no exception. They are black/brown and have two yellow marks along the dorsal midline (spine). One mark is longer than the other. This species also has a long horn near the head. It is an extension of the pronotum (shoulder area).

    Two-Marked Treehoppers can be a pest. They weaken plants with their consistent feeding from the stems and leaves. This leads to browning and death. The treehopper can also secrete a sweet sticky substance called honeydew. This attracts other insects and can promote mold growth that looks like a black soot or ash.

    Popultions of Two-Marked Treehoppers are host specific, yet each seems to feed on a different plant making interactions between populations a bit complicated. They are able to travel to other areas and if they encounter another Two-Marked Treehopper that has always fed from a different plant, the likelihood of the two reproducing greatly diminishes. It's not impossible that the two will mate, just less probable than if a male and female on the same diet would meet.

    BUGFINDER: What Kind of Bug is This...
    BUGFINDER allows for a quick search of the Insect Identification database by selecting primary color, secondary color, number of legs and the territory / state in question. If only one color is present on your insect, select it again as its SECONDARY color. Remember that the more details you can offer, the better your chances of finding a match. As a rule of thumb, six legs are typical for most insects whereas spiders generally have eight legs.
