"You better not fool with a Bumblebee!— Ef you don't think they can sting—you'll see! " ~ James Whitcomb Riley, "The Bumblebee"
Even though humans can see more colors, bees have a much broader range of color vision. Their ability to see ultraviolet light gives them an advantage when seeking nectar. Some flowers such as sunflowers, primroses and pansies have nectar guides that can only be seen in ultra-violet light!
World Bee Day is celebrated on the day Anton Janša, a pioneer of modern apiculture, was born in 1734. He is noted for his expertise, lectures, and books on the field of beekeeping as well as changing the size and shape of hives to a form where they can be stacked together like blocks.
The purpose of this international day is to acknowledge the role of bees and other pollinators for the ecosystem.
This tartan, designed by Carol A.L. Martin, is inspired by a bumble bee collecting pollen from pink flowers.
The word "bumblebee" is a compound word of "bumble" + "bee" — "bumble" meaning to hum, buzz, drone, or move ineptly or flounderingly.
According to the Oxford English Dictionary, the term "bumblebee" was first recorded as having been used in the 1530 work Lesclarcissement by John Palsgrave, "I bomme, as a bombyll bee dothe." However, it also states that the term "humblebee" predates it, having first been used in 1450 in Fysshynge wyth Angle, "In Juyll the greshop & the humbylbee in the medow."
The latter term was used in A Midsummer Night's Dream (circa 1600) by William Shakespeare, "The honie-bags steale from the humble Bees." An old provincial name, "dumbledor", also denoted a buzzing insect such as a bumblebee or cockchafer, "dumble" probably imitating the sound of these insects, while "dor" meant "beetle".
Bumblebees are social insects which form colonies with a single queen. Colonies are smaller than those of honeybees, sometimes as few as 50 individuals in a nest. Female bumblebees can sting repeatedly, but generally ignore humans and other animals.
Like honeybees, bumblebees feed on nectar and gather nectar to add to the stores in the nest, and pollen to feed their young. They forage using colour and spatial relationships to identify flowers to feed from. Some bumblebees rob nectar, making a hole near the base of a flower to access the nectar while avoiding pollen transfer.
Bumblebees are important pollinators of both crops and wildflowers. Because bumblebees do not overwinter the entire colony, they do not stockpile honey, so are not useful as honey producers. Bumblebees are increasingly cultured for agricultural use as pollinators, among other reasons because they can pollinate plants such as tomatoes in greenhouses by buzz pollination (moving their flight muscles rapidly to shake loose pollen) whereas other pollinators cannot.
According to late 20th-century folklore which you may have come across, "the laws of aerodynamics prove the bumblebee should be incapable of flight, as it does not have the capacity (in terms of wing size or beats per second) to achieve flight with the degree of wing loading necessary."
