The study of the proboscis of butterflies revealed surprising examples of adaptations to different kinds of fluid food, including nectar, plant sap, tree sap, dung and of adaptations to the use of pollen as complementary food in Heliconius butterflies. The study of insect mouthparts was helpful for the understanding of the functional mechanism of the proboscis of butterflies (Lepidoptera) to elucidate the evolution of new form-function. Others, such as the family Micropterigidae, have mouth parts of the chewing kind. Ī few Lepidoptera species lack mouth parts and therefore do not feed in the imago. In this species, the moth hovers in front of the flower and extends its long proboscis to attain its food. ![]() A specific example of the proboscis being used for feeding is in the species Deilephila elpenor. Suction takes place due to the contraction and expansion of a sac in the head. ![]() Each tube is inwardly concave, thus forming a central tube up which moisture is sucked. The proboscis contains muscles for operating. The proboscis consists of two tubes held together by hooks and separable for cleaning. The mouth parts of Lepidoptera mainly consist of the sucking kind this part is known as the proboscis or 'haustellum'. The Acanthocephala or thorny-headed worms, or spiny-headed worms are characterized by the presence of an eversible proboscis, armed with spines, which it uses to pierce and hold the gut wall of its host.
