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.
Within the Neuropterida, adults have chewing mouthparts, but the mandibles of male dobsonflies are non-functional in feeding. The larvae in many lineages are predatory, with mandibles modified with grooves along which digestive saliva flows, while the larvae of the family Sisyridae have the mouthparts developed into a sucking tube which they ...
Glossina adult tsetse fly; piercing mouthparts conspicuous. There is one genus in this Family: Glossina, known as tsetse-flies or simply tsetse. [38] Flies of this family are similar to Stomoxys flies within the Muscidae, but have a life cycle and veterinary and medical importance justifying a separate Family designation. Tsetse-flies are found ...
Head of a horse-fly showing large compound eyes and stout piercing mouthparts A head of a fly, showing the two compound eyes and three simple eyes clearly. Flies have a mobile head with a pair of large compound eyes on the sides of the head, and in most species, three small ocelli on the top. The compound eyes may be close together or widely ...
An insect uses its digestive system to extract nutrients and other substances from the food it consumes. [3]Most of this food is ingested in the form of macromolecules and other complex substances (such as proteins, polysaccharides, fats, and nucleic acids) which must be broken down by catabolic reactions into smaller molecules (i.e. amino acids, simple sugars, etc.) before being used by cells ...
Adult horse-flies feed on nectar and plant exudates; males have weak mouthparts, but females have mouthparts strong enough to bite large animals. This is for the purpose of obtaining enough protein from blood to produce eggs. The mouthparts of females are formed into a stout stabbing organ with two pairs of sharp cutting blades, and a ...

They are typically the largest mouthparts of chewing insects, being used to masticate (cut, tear, crush, chew) food items. They open outwards (to the sides of the head) and come together medially. In carnivorous, chewing insects, the mandibles can be modified to be more knife-like, whereas in herbivorous chewing insects, they are more typically ...
