“…The labium constitutes the bottom, the stipites including the laciniae and galeae form the sides and the labrum/epipharynx composes the roof of this short temporary food tube (Duncan 1939) which was termed "Wespenrüssel" (Kirmayer 1909) or "wasp proboscis". The glossae and paraglossae produce lapping motions, similar to the "licking cycle" in honey bees (Snodgrass 1956, Wu et al 2015. In the extended position of the ligula, liquid adheres to the spatula-shaped microtrichia that is thus transported into the food canal when the glossae and paraglossae are retracted towards the mouth (Seifert 1995).…”

Social wasps perform a variety of tasks with their mouthparts. Female workers use them to feed on carbohydrate-rich fluids, to build nests by collecting wood fibers and forming paper, to hunt and manipulate insect prey for feeding larvae as well as for brood care. Since male wasps neither feed on insects nor participate in nest building, sex-specific differences in mouthpart morphology are expected. Despite these different applications, general mouthpart morphology of male and female wasps from the genus Vespula was similar. However, males possessed significantly shorter mandibles with fewer teeth than females. Furthermore, the adductor muscles of the mandibles were distinctly smaller in males than in females. Male wasps showed a higher number of sensilla on the mandibles and the labial palpi. Mouthpart dimorphism and functional morphology of fluid uptake are discussed.

“…In addition, a similar feeding mechanism might take place in other, more distantly related insect groups. The mouthparts of the nectar-feeding cricket Glomeremus orchidophilus Hugel et al (Gryllacrididae) [38] and the honeybee Apis mellifera L. (Apidae), for instance, might also involve the employment of capillary action [39][40][41], and exhibit a relationship between the sizes of spaces between their mouthpart structures and the sizes of substrate pores from which they can feed.…”

Mouthpart conduit sizes of fluid-feeding insects determine the ability to feed from pores

Fluid-feeding insects, such as butterflies, moths and flies (20% of all animal species), are faced with the common selection pressure of having to remove and feed on trace amounts of fluids from porous surfaces. Insects able to acquire fluids that are confined to pores during drought conditions would have an adaptive advantage and increased fitness over other individuals. Here, we performed feeding trials using solutions with magnetic nanoparticles to show that butterflies and flies have mouthparts adapted to pull liquids from porous surfaces using capillary action as the governing principle. In addition, the ability to feed on the liquids collected from pores depends on a relationship between the diameter of the mouthpart conduits and substrate pore size diameter; insects with mouthpart conduit diameters larger than the pores cannot successfully feed, thus there is a limiting substrate pore size from which each species can acquire liquids for fluid uptake. Given that natural selection independently favoured mouthpart architectures that support these methods of fluid uptake (Diptera and Lepidoptera share a common ancestor 280 Ma that had chewing mouthparts), we suggest that the convergence of this mechanism advocates this as an optimal strategy for pulling trace amounts of fluids from porous surfaces.

“…The dimensions of glossal hairs of the Italian honeybee (Apis mellifera ligustica) were examined by (Amirouche et al, 2009) and they found that the average length of hairs increased from the proximal segment to the distal end. Wu et al (2015) discovered the function of the glossal hair and reported that when drinking nectar, the glossal hairs erected rhythmically; specifically, hairs on the proximal segment erected before those on the distal end of a honeybee's tongue, and this was described as asynchronous hair erection. Moreover, they found that the flabellum was the most hydrophilic and the root of the tongue was hardest to be wetted by measuring the wettability of the tongue.…”

“…The nectar drinking strategy has been studied extensively and the erection of glossal hairs has been revealed in several researches (Cook, 1880;Snodgrass, 1956;Dade, 2009). The rhythmical erection pattern of honeybees' glossal hairs in nectarfeeding has been reported, but the role of the deformable tongue structure in nectar-feeding has not been investigated yet (Wu et al, 2015). In this work, we focused on the deformation of the proboscis formation of honeybees, especially the morphing of the hair pattern, and its supposed influence on the feeding type and efficiency.…”

The morphological characters of honeybees were measured using a Scan Photo technique (SPT) that involves the use of a stereo binocular microscope and Photoshop program combined together. The body parts of a honeybee worker were scanned as images after they have been dissected. Photoshop program was used to view the images and their characters were measured using the ruler of the software program. While measuring the chosen morphometric characters, a significant difference was observed when the SPT and using a binocular microscope were compared. The measurements of 7 morphological characters of honeybee workers from nectar-feeding colonies were compared with those of Pepsi cola feeding colonies. There are more than 24 different subspecies of honeybees (Apis mellifera) classified based on their morphological characteristics. As a result, morphological characteristics are usually considered when classifying honeybees. Many authors for various reasons have used body morphological characteristics as well as sets of wings to classify subspecies of honeybees. Such characteristics have been defined overtime and sourced from diverse studies. Of all body morphological characteristics studied so far, wing venation characteristics have been given more attention. Up to now in Saudi Arabia, there are no specific review articles that focus mainly on Apis mellifera jemenitica body morphological characteristics. Consequently, information gathered from sampling and measurement methods, and factors affecting these characteristics especially mouthparts is to recognize the possibility of finding any changes in configuration as a result of feeding on soft drink. The morphology and functional anatomy of the mouthparts are examined by dissection, light microscopy, and supplemented by feeding type observations. This manuscript focuses on the differentiation of the proboscis which is formed by the glossa, in context with feeding from natural nectar and soft drink. In the literature, morphological innovations have been described for insects, particularly forbees.These innovations are critical for the production of differentiation in proboscis such as proboscis hair formation and modification. The present study showed that the proboscis of honeybees feeding on Pepsi is wider, thicker and very hairy compared to the natural feeding honeybee's proboscis. The morphological structures of the head, proboscis, hind leg, and wings were measured for the two groups of bees, the first naturally nourished with nectar, and the second feeding on the drink Pepsi Cola. The results showed significant differences in nectar and Pepsi feeding in different length measurements of head (
