The Zayante band-winged grasshopper (Trimertropis infantilis) has been listed as an endangered species. [2] [3] The main threat to the species is habitat loss. The introduction of non-native plant species of plants has also impacted the grasshopper populations. Over-collection and pesticides have been identified as potential threats. [4]
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; the volatile organic compounds are attractive to predators of the herbivorous insects.
Grasshoppers eat large quantities of foliage both as adults and during their development, and can be serious pests of arid land and prairies. Pasture, grain, forage, vegetable and other crops can be affected. Grasshoppers often bask in the sun, and thrive in warm sunny conditions, so drought stimulates an increase in grasshopper populations.
Grasshoppers in general, including this species, are herbivorous and subsist mainly on grasses. [6] Scientists have gained knowledge of the diet of G. rufus through the use of feces as a source of DNA. It has been documented to eat plants of the genus Bromus, the species Holcus lanatus, and the subfamily Pooideae, all within the family Poaceae. [6]
Dissosteira carolina feeds on both grasses and forbs, but the actual composition of the diet depends on habitat.For example, in a disturbed site that had been reseeded with Bromus inermis and Agropyron cristatum, when the adults' crop contents were examined, 98 percent of the food consumed was Bromus inermis.
This species is a folivore, essentially feeding on leaves of various plants. [4] It is a solitary species, harmless to crops. Adults are mainly seen in August and September, but they are active throughout the year. [3] [4] After mating, these grasshoppers overwinter as adults.
Schistocerca nitens is a species of grasshopper known by several names, including vagrant grasshopper and gray bird grasshopper.

This grasshopper is native to southern North America including Mexico and the south-western United States from California to Texas. Vagrants are ...
