Some moths do not feed after emerging from the pupa, and have greatly reduced, vestigial mouthparts or none at all. All but a few adult Lepidoptera lack mandibles (the superfamily known as the mandibulate moths have fully developed mandibles as adults), but also have the remaining mouthparts in the form of an elongated sucking tube, the proboscis.
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 ...
Haematobia irritans, the horn fly, is a small fly (about half the size of a common housefly). It was first described by Carl Linnaeus in his 1758 10th edition of Systema Naturae . It is of the genus Haematobia which is the European genus of bloodsucking flies.
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 ...
The primary function of the adult is reproduction; adults do not feed and have only vestigial mouthparts, while their digestive systems are filled with air. [13] Dolania americana has the shortest adult lifespan of any mayfly: the adult females of the species live for less than five minutes.
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 ...
Due to their species ambiguity and this diversity of behaviors, there is much controversy in research on their feeding habits, particularly as adults. Many reference sources in the past century or so have repeated the assertion that the chironomidae do not feed as adults, but an increasing body of evidence contradicts this view.
