I happened to flush one of these creatures out of its hiding spot while walking through a field in southern Illinois. It did not just hop a few feet in front of me, like most grasshoppers, rather it took wing, flying several hundred feet and landing in high up in a tree.

Although these large insects have two generations a year, they are most abundant in the Autumn. Mature females are approximately two inches in length, and the males are only slightly smaller. They are North America’s largest flying grasshoppers.

While most grasshoppers overwinter as eggs in the soil, American Bird Grasshoppers overwinter as adults and lethargically active adults can be spotted on warm Winter days in meadows and along wooded edges throughout the colder months.

The American Bird Grasshopper is found in fields and open woodlands in eastern and central North America, south into Mexico and South America. Somewhat migratory, in the northern part of range it may be an immigrant only and not breed.

This species was the source of a newly discovered class of chemical compounds called caeliferins. When the grasshopper feeds on a plant, its caeliferins induce the plant to release volatile organic compounds. Caeliferins also play a role in defense, as the grasshopper expels large amounts of it when attacked.

Not only is its large size impressive, I found its detailed Art Deco-like pattern really neat.
