Typically the mandibles are the largest and most robust mouthparts of a chewing insect, and it uses them to masticate (cut, tear, crush, chew) food items. Two sets of muscles move the mandibles in the coronal plane of the mouth: abductor muscles move insects' mandibles apart ( laterally ); adductor muscles bring them together ( medially ).
Housefly mouthparts, showing the pseudotracheae, semitubular grooves (dark parallel bands) used for sucking up liquid food. The mouthparts are specially adapted for a liquid diet; the mandibles and maxillae are reduced and not functional, and the other mouthparts form a retractable, flexible proboscis with an
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 ...
The mouthparts of orthopteran insects are often used as a basic example of mandibulate (chewing) mouthparts, and the mandibles themselves are likewise generalized in structure. They are large and hardened, shaped like pinchers, with cutting surfaces on the distal portion and chewing or grinding surfaces basally .
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 ...
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 ...
Black flies are the main biting fly in the Upper Peninsula, although people tend to encounter them most near creeks and rivers where their larvae hatch from, appearing mostly in the spring through ...
Diptera is an order of winged insects commonly known as flies. Diptera, which are one of the most successful groups of organisms on Earth, are very diverse biologically. None are truly marine but they occupy virtually every terrestrial niche. Many have co-evolved in association with plants and animals.
