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 ...
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 ...
A few Lepidoptera species have reduced mouthparts and do not feed in the adult state. Others, such as the basal family Micropterigidae, have chewing mouthparts. [21] The proboscis (plural – proboscises) is formed from maxillary galeae and is adapted for sucking nectar. [3] It consists of two tubes held together by hooks and separable for ...
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 ...
Mandibulate mouthparts, among the most common in insects, are used for biting and grinding solid foods. Piercing-sucking mouthparts have stylets and are used to penetrate solid tissue and then suck up liquid food. Sponging mouthparts are used to sponge and suck liquids, and lack stylets (e.g. most Diptera).
This process leaves cells destroyed or collapsed, and a distinctive silvery or bronze scarring on the surfaces of the stems or leaves where the thrips have fed. [16] The mouthparts of thrips have been described as “rasping-sucking”, [17] “punching and sucking”, [11] or, simply just a specific type of “piercing-sucking” mouthparts. [18]
Most adults have short lives during which they do not feed. In fly fishing, artificial flies called dry flies are tied to imitate adults, while larvae and pupae are imitated with artificial flies called wet flies or nymphs. It is also possible to use them as bait, though this is not as common as artificial flies and is known as bait fishing.
