In most grasshopper species, conflicts between males over females rarely escalate beyond ritualistic displays. Some exceptions include the chameleon grasshopper (Kosciuscola tristis), where males may fight on top of ovipositing females; engaging in leg grappling, biting, kicking and mounting. [42]
This species was the source of a newly discovered class of chemical compounds called caeliferins. These are fatty acid chains present in the grasshopper's regurgitant. When the grasshopper feeds on a plant, the caeliferins in the regurgitant induce the plant to release volatile organic compounds. This is a common response to herbivory in plants ...
Acrididae are the predominant family of grasshoppers, comprising some 10,000 of the 11,000 species of the entire suborder Caelifera. The Acrididae are best known because all locusts (swarming grasshoppers) are of the Acrididae.

Species such as the Senegalese grasshopper (Oedaleus senegalensis) [30] and the African rice grasshopper (Hieroglyphus daganensis), both from the Sahel, often display locust-like behaviour and change morphologically on crowding. [30] North America is the only sub-continent besides Antarctica without a native locust species.
