Small but mighty, the Two-marked Treehopper is an able jumper and flier, nimbly moving from branch to branch on trees and plants.
Treehoppers are a plant-sucking insect that have the ability to leap both 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 plant browning and possible 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.
Populations of Two-marked Treehoppers are host specific, yet each localized group seems to feed on a different plant making interactions between nearby populations a bit complicated. They easily travel to other areas, and if they encounter another population of Two-Marked Treehoppers that feeds from a different plant, the two groups may never meet and reproduction between them greatly diminishes. It is not impossible that the two populations will interbreed, just less probable than if a male and female on the same diet would meet.

Note: An insect's reach is not limited by lines drawn on a map and therefore species may appear in areas, regions and/or states beyond those listed above as they are driven by environmental factors (such as climate change), available food supplies and mating patterns. Grayed-out selections indicate that the subject in question has not been reported in that particular territory. U.S. states and Canadian provinces / territories are clickable to their respective bug listings.
