The Eastern Lubber Grasshopper is one of the largest and slowest moving grasshoppers and can reach 3 inches in length.
The bright colors and patterning on the Eastern Lubber Grasshopper is a warning pattern to predators that they are poisonous. They ingest and assimilate substances in the plants they consume that, although harmless to humans and the lubbers themselves, are toxic to many predators. They don’t bite but they do spit. When startled, Eastern Lubber Grasshoppers will spread their wings, hiss, and expel a fine spray of toxic chemicals for a distance of 6 inches.
Darker forms of the Eastern Lubber Grasshopper also exist, where the yellow color becomes the minor rather than the major color component, and in northern Florida, a predominantly black form is sometimes found.
