Orthoptera (from Ancient Greek ὀρθός (orthós) 'straight' and πτερά (pterá) 'wings') is an order of insects that comprises the grasshoppers, locusts, and crickets, including closely related insects, such as the bush crickets or katydids and wētā. The order is subdivided into two suborders: Caelifera – grasshoppers, locusts, and ...
Mole crickets are members of the insect family Gryllotalpidae, in the order Orthoptera (grasshoppers, locusts, and crickets). Mole crickets are cylindrical-bodied, fossorial insects about 3–5 cm (1.2–2.0 in) long as adults, with small eyes and shovel-like fore limbs highly developed for burrowing. They are present in many parts of the world ...
The Caelifera are a suborder of orthopteran insects. [2] They include the grasshoppers and grasshopper-like insects, as well as other superfamilies classified with them: the ground-hoppers (Tetrigoidea) and pygmy mole crickets (Tridactyloidea). The latter should not be confused with the mole crickets (Gryllotalpidae), which belong to the other ...
Mandible (insect mouthpart) Insect mandibles are a pair of appendages near the insect's mouth, and the most anterior of the three pairs of oral appendages (the labrum is more anterior, but is a single fused structure). Their function is typically to grasp, crush, or cut the insect's food, or to defend against predators or rivals.
Chewing insects. The trophi, or mouthparts of a locust, a typical chewing insect: 1 Labrum. 2 Mandibles; 3 Maxillae. 4 Labium. 5 Hypopharynx. Examples of chewing insects include dragonflies, grasshoppers and beetles. Some insects do not have chewing mouthparts as adults but chew solid food in their larval phase.
Individual adults of S. scapterisci are either male or female and their entire life cycle takes place within the host insect. This comprises an egg stage, four larval stages, the third of which is infective, and an adult stage. Depending on the conditions and the abundance of the parasite, there is either a short life cycle or a long one.
In general, arthropods have mouthparts for cutting, chewing, piercing, sucking, shredding, siphoning, and filtering. This article outlines the basic elements of four arthropod groups: insects, myriapods, crustaceans and chelicerates. Insects are used as the model, with the novel mouthparts of the other groups introduced in turn.
The desert locust is a species of orthopteran in the family Acrididae, subfamily Cyrtacanthacridinae. [2] There are two subspecies, one called Schistocerca gregaria gregaria, the better known and of huge economic importance, located north of the equator, and the other, Schistocerca gregaria flaviventris, [9] [10] which has a smaller range in south-west Africa and is of less economic importance ...
