Many undescribed species probably exist, especially in tropical forests. The Caelifera have a predominantly tropical distribution (as with most Orthoptera) with fewer species known from temperate climate zones. Caelifera are divided into two infraorders: the more basal Tridactylidea and the Acrididea or grasshopper-like species.
Pseudochorthippus parallelus [1] (often known by its synonym Chorthippus parallelus), the meadow grasshopper, [2] is a common species of grasshopper in the tribe Gomphocerini. [3] It is found in non-arid grasslands throughout the well vegetated areas of Europe and some adjoining areas of Asia.
Nestedness: the degree to which species with few links have a sub-set of the links of other species, rather than a different set of links. In highly nested networks, guilds of species that share an ecological niche contain both generalists (species with many links) and specialists (species with few links, all shared with the generalists).

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.
Acrididea including the Acridomorpha [3] is an infraorder of insects that describe the grasshoppers (thus also locusts) and ground-hoppers. It contains a large majority of species in the suborder Caelifera and the taxon Acridomorpha may also be used, which excludes the Tetrigoidea . [ 4 ]
Chorthippus brunneus, also known as the common field grasshopper, is a species of grasshopper of the subfamily Gomphocerinae. [1] The species is common and widespread in the Western Palearctic , and the IUCN lists it as Least Concern .

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 ...
