Hydrophilic and opened canals in honey bee tongue rods endow elastic structures with multiple functions.

Acta Biomater 2022 01 27;137:162-171. Epub 2021 Oct 27.

Functional Morphology and Biomechanics, Zoology Department, Kiel University, Am Botanischen Garten 9, 24118 Kiel, Germany.

The honey bee (Apis mellifera L.) tongue is a sophisticated and dexterous probing device that can bend and twist, adapting to various surfaces for liquid imbibition and/or gustatory sensing. The tongue exhibits remarkable extendibility, flexibility, and durability, which may be essentially ascribed to the internal elastic rod that supports the entire tongue. Read More

Nectar Feeding by a Honey Bee's Hairy Tongue: Morphology, Dynamics, and Energy-Saving Strategies.

Insects 2021 Aug 24;12(9). Epub 2021 Aug 24.

School of Aeronautics and Astronautics, Sun Yat-Sen University, Guangzhou 510006, China.

Most flower-visiting insects have evolved highly specialized morphological structures to facilitate nectar feeding. As a typical pollinator, the honey bee has specialized mouth parts comprised of a pair of galeae, a pair of labial palpi, and a glossa, to feed on the nectar by the feeding modes of lapping or sucking. To extensively elucidate the mechanism of a bee's feeding, we should combine the investigations from glossa morphology, feeding behaviour, and mathematical models. Read More

How honey bees dip nectar: Dynamic spacing of tongue hairs facilitates to collect nectar of various viscosities.

J Theor Biol 2021 03 12;512:110538. Epub 2020 Nov 12.

School of Aeronautics and Astronautics, Sun Yat-Sen University, Guangzhou 510006, People's Republic of China.

A honey bee can dip nectar of viscosity across two orders of magnitude, by viscous lapping technique using a segmental tongue covered with erectable hairs. The drinking technique suffers risks of leakage occurring between tongue hairs, and the amount of leakage is related to hair spacing as well as nectar viscosity. When lapping, tongue segments are elongated, which enlarges the hair spacing in longitudinal direction. Read More

Drinking made easier: honey bee tongues dip faster into warmer and/or less viscous artificial nectar.

J Exp Biol 2020 09 24;223(Pt 18). Epub 2020 Sep 24.

School of Aeronautics and Astronautics, Sun Yat-Sen University, Guangzhou 510006, People's Republic of China.

Optimal concentrations for nectar drinking are limited by the steep increase in the viscosity of sugar solutions with concentration. However, nectar viscosity is inversely related to temperature, which suggests there are advantages to foraging from flowers that are warmer than the surrounding air. The honey bee ( L. Read More

Feeding behavior of honey bees on dry sugar.

J Insect Physiol 2020 07 21;124:104059. Epub 2020 May 21.

School of Aeronautics and Astronautics, Sun Yat-Sen University, Guangzhou 510006, China.

The feeding habits of insects can be influenced by food abundance, nutrition, physical forces, and many other variables, which is why this topic is multidisciplinary and perennially fascinating. Although honey bees primarily feed on liquid nectar, they also can feed on dry sugar; however, the feeding mechanism for feeding on dry substances by a primarily fluid-feeding insect remains unexplored. We observed that, when honey bees are accessible to both dry sugar and liquid nectar, they prefer to feed on the latter. Read More
