Summary

The Chortophagini tribe encompasses a group of grasshoppers native to North America, characterized by their preference for moist habitats and several morphological traits that can vary between species.

Physical Characteristics

Most species of Chortophagini are rather smooth. The mid-dorsal ridge on the pronotum is typically obvious and cut only once, except for a few genera like Machaerocera and Shotwellia, which have a low, notched ridge. The fastigium is often narrow, with prominent raised margins, and the coloration of the body can include green, with wings usually being clear or somewhat yellowish with dark bands. Many species exhibit a darkened stigma at the hind wing's front edge.

Identification Tips

Look for a diagonal line on the color pattern of the eyes and a narrow, impressed fastigium. The mid-dorsal ridge of the pronotum can be a key identifying feature. Also, observe the wing coloration, which can vary significantly among species.

Habitat

Chortophagini species prefer moist meadowy environments such as stream margins, grassy meadows, woodland openings, and even alkali depressions, usually associated with rank grass or sedge growth.

Distribution

Primarily distributed in North America, with a notable presence in moist meadows and fields.

Diet

Chortophagini are herbivorous, feeding on various grasses and plants within their habitat.

Predators

Birds, small mammals, and other insectivorous animals are likely predators of Chortophagini grasshoppers, as is typical for many grasshopper species.

Ecosystem Role

As herbivores, Chortophagini play an important role in the ecosystem by influencing plant community dynamics and serving as prey for higher trophic levels.

Economic Impact

Some species are considered important locusts and may affect agriculture when populations are dense, such as Locusta migratoria and Chortoicetes terminifera.

Collecting Methods

• Hand collection
• Sweep nets
• Pitfall traps

Preservation Methods

• Ethanol preservation
• Pinning specimens
• Drying

Evolution

Chortophagini may share evolutionary close ties with the tribes Encoptolopus and Machaerocerini, as suggested by recent molecular studies.

Similar Taxa

• Encoptolophus
• Machaerocera
• Melanotettix

Misconceptions

They can be mistaken for locusts or other grasshoppers due to their appearance and behavior, particularly when they camouflage within grass.
