Honey bees can use polarized light on overcast days to estimate the position of the Sun in the sky, relative to the compass direction they intend to travel. Karl von Frisch 's work established that bees can accurately identify the direction and range from the hive to a food source (typically a patch of nectar-bearing flowers).
To get the honey beekeepers either drove the bees out of the skep or, by using a bottom extension called an eke or a top extension called a cap, sought to create a comb with only honey in it. Quite often the bees were killed, sometimes using lighted sulfur, to allow the honeycomb to be removed. Skeps could also be squeezed in a vise to extract ...
Their ability to do this is known as social homeostasis and was first described by Gates in 1914. [71] During hot weather, bees cool the hive by circulating cool air from the entrance through the hive and out again; [72] and if necessary by placing water, which they fetch, throughout the hive to create evaporative cooling. [73]
They lack external entrance tunnels, but do build internal entrance tunnels where guard bees patrol, looking out for any intruders (including Small Hive Beetle, Phorid Fly, and other bees). [6] T. carbonaria builds brood cells arranged in combs or semicombs. The cells are a single layer of hexagonal combs that are built in a distinctive spiral.
He demonstrated that bees can recognize a desired compass direction in three different ways: by the Sun, by the polarization pattern of the blue sky, and by the Earth's magnetic field. He showed that the Sun is the preferred or main compass; the other mechanisms are used under cloudy skies or inside a dark beehive . [ 67 ]
It is shiny, fully black in colour with fuscous metallic blue-green or purple wings in sunlight. The broad-handed carpenter bee is among the largest Xylocopa known and among the largest bees of the world (though it is not the world's largest, that title belongs to another Southeast Asian bee, the Indonesian Megachile pluto). It has a loud and ...

A bumblebee (or bumble bee, bumble-bee, or humble-bee) is any of over 250 species in the genus Bombus, part of Apidae, one of the bee families. This genus is the only extant group in the tribe Bombini, though a few extinct related genera (e.g., Calyptapis) are known from fossils.
