Like all bee tongues, the bumblebee tongue (the proboscis) is a long hairy structure that extends from a sheath-like modified maxilla. Bumblebees form colonies, which are usually much less extensive than those of honey bees. humans) unless disturbed. The sound is actually the result of the bee vibrating its flight muscles, and this can be achieved while the muscles are decoupled from the wings. The adult flies like deadnettle and primrose flowers. The proboscis is also used to clean their hairs or to groom one another, especially the queen. Bee Identification Bees, like other Hymenoptera, have three body segments; a head, thorax, and abdomen. Across all combinations of bumble bee species and caste, excluding the nectar-robbing species B. occidentalis, there was the expected positive relationship between bumble bee proboscis length and the average corolla length for recorded flower visits (r 2 =0.7, P < 0.001; Fig. While foraging, bumblebees can reach ground speeds of up to 15 metres per second (54 km/h). In 1934, French entomologist Antoine Magnan (1881-1938) included the following passage in the introduction to his book Le Vol des Insectes: Tout d’abord poussé par ce qui se fait en aviation, j’ai appliqué aux insectes les lois de la résistance de l’air, et je suis arrivé avec M. Sainte-Laguë à cette conclusion que leur vol est impossible. Males in particular are forcibly driven out by the workers. The bumblebee uses its proboscis to collect pollen and nectar. The distribution of worker proboscis lengths among species in the species-pool in Kent is clumped about a median of 7.9 mm. The main concentration of these hairs are on the antenna and mouthparts (this page). Non-fertilised eggs become males, and only fertilised eggs grow into females and queens. Bumble Bee-Mimicking Robber Flies. The diversity of the more than 250 bumble bee species means a wide variety of proboscis (tongue) lengths, allowing the pollination of a wide variety of plants. These bees don’t have barbed stingers, so they … Of these, three have been extirpated, eight are in serious decline, and only six remain widespread. Similar declines in bumblebees have been reported in Ireland, with 4 species being designated endangered, and another two species considered vulnerable to extinction.  A decline in bumblebee numbers could cause large-scale changes to the countryside, resulting from inadequate pollination of certain plants. Special features: Bee flies look more like a bee than a fly - hence the name. Further information: Bumblebee communication, A bumblebee loaded with pollen in itspollen baskets, Main article: List of crop plants pollinated by bees, A widely believed falsehood holds that scientists proved that bumblebees are incapable of flight, Buff-tailed bumblebee, or large earth bumblebee,Â. Other bees have similar physiology, but the mechanisms have been best studied in bumblebees. Female cuckoo bumblebees will aggressively attack host colony members, and sting the host queen, but will ignore other animals (e.g. [3],, Creative Commons Attribution-ShareAlike License, This page was last edited on 10 September 2020, at 13:27. The archaic English colloquialism dumbledor (also used for cockchafers) is the source of the name Albus Dumbledore, a fictional character from the Harry Potter series (1997-2007). J. K. Rowling said the name “seemed to suit the headmaster, because one of his passions is music and I imagined him walking around humming to himself”.The orchestral interlude Flight of the Bumblebee was composed (circa 1900) by Nikolai Rimsky-Korsakov to represent the turning of Prince Guidon to visit his father, Tsar Saltan, in the opera The Tale of Tsar Saltan, although the music is considered to more accurately reflect the flight of a bluebottle than a bumblebee. The music inspired Walt Disney to feature a bumblebee in his 1940 animated musical Fantasia and have it sound as if it were flying in all parts of the theater. New queens and males leave the colony after maturation. A bumble bee  is any member of the bee genus Bombus, in the family Apidae. In the early spring, the queen comes out of diapause and finds a suitable place to create her colony. European bumblebees have also been introduced to … These pupae then develop into adult bees, and chew their way out of the silk cocoon. Once the queen finds a site, she prepares wax pots to store food, and wax cells to lay eggs in. Relative to the size of the average honey bee, the proboscis is long, a result of evolution helping the bee to reach the center of a flower to collect nectar. At the end of the assay, we gave the bees a 30-min resting period under red light. are surrounded in a reservoir of blood. Abstract. Spotting these insects won't win you any points during the Great British Bee Count. on the species with long corollas. The queens can live up to one year, possibly longer in tropical species. The B. major bee-fly is a common, generalist floral pollinator, meaning that it does not give preference to one flower over another, instead pollinating a wide variety of plant families and species.
