found from three websites is also called "Werbetanz". When the worker bees of bees go out and find nectar or pollen returning to their nests, they go to the dense bee colony on the nest spleen, while violently vibrating their bellies, and make a circling action by walking in a figure of eight, which is analyzed in detail by K. von Frisch. This is a form of informing the worker bees in the same nest that the honey source exists, and informing other worker bees. When the distance between the honey source and the nest is more than 1 meters, keep a certain angle to the direction of gravity, draw a straight line first, then rotate to the right or left, and then restore the original position. In this case, the angle formed by the straight line and the direction of gravity is the same as that formed by the direction of the sun and the direction of food when viewed from the hive. In addition, the frequency and distance of the dancing fast man are inversely proportional to the intermittent wing vibration at that time, which also conveys the distance of the honey source. Dancing.

frisch's research points out that a large number of worker bees send "scout bees" to look for honey sources before they leave their nests to collect honey. Once these "scouts" find favorable honey collecting sites or new high-quality honey source plants, they will become collecting bees, fly back to the hive and jump on a circle dance or a figure-of-eight dance to point out the location of food, express the distance from the hive to the honey source with the speed of dance, and inform the food with the smell of pollen attached to them. Inform everyone to gather honey together. When the scout bees find the honey source within 1 meters from the hive, they will report back to the nest. Besides leaving the tracking information, they will alternately turn small circles to the left or right on the hive and crawl in a "round dance" way.

If the honey source is 1 meters away from the hive, the scout bees will change their dance posture to "∞", so it is also called "8-character dance". If it lasts for 2 seconds, it will be about l meters. < P > The distance between the honey source and the hive is directly related to the speed of the dance. The closer the distance, the faster the turn and the faster the crawling. The farther the distance, the slower the turn and the slower the movement. The dancing action of bees can not only report the distance between the nectar and the nest, but also indicate the direction in which the nectar is located. If the bees are dancing with their heads up, it means: "Fly in the direction of the sun, and you can find pollen." On the contrary, it means: "Food can be found in the place facing away from the sun."

In the warm season of spring. Some bees doing reconnaissance fly out of the box to look for the honey source. When the reconnaissance bees find the honey source outside, they suck up some nectar and pollen and fly back quickly. When they return to the hive, they keep dancing. Don't think that this is just a show of joy, in fact, this dance is used by bees to indicate the distance and direction of the honey source. There are two kinds of bee dances: round dance and figure-eight dance. If the honey source found is not too far from the hive, If the honey source is far away, perform a figure-of-eight dance. When dancing, if the head is up, the honey source is facing the sun, and if the head is down, the honey source is facing away from the sun.

The bees in the hive got the good news brought by the reconnaissance bees, and some quickly flew out of the box and flew in the direction it guided. After these out-of-home bees returned from eating nectar, they also flew to their companions. Mobilize everyone to collect honey. In this way, more and more bees rush to the honey source and do a lot of collection work. ZYDG/Puter/Book/Read/Artimage/2721/VT5 _ 2.jpg

Bees determine the direction of the sun according to the polarized light of the sun, so they can indicate the direction of the honey source by the sun beacon. Reconnaissance bees dance. Other worker bees followed closely, and then flew out to look for flowers with the same smell according to the smell of nectar on the dancing bees. The more nectar, the sweeter it is, and the more vigorous the dance of the reconnaissance bees will be, which not only speeds up the pace, but also lasts for a long time, as if to say, "Let's go and collect nectar!" If the reconnaissance bee finds the honey source further away, it will use the more complicated "figure-eight dance" to inform other worker bees. When the part of the route connecting the two rings of the figure-eight (straight running) dances, the bee also swings its tail quickly, so it is also called "tail-wagging dance". The number of dances completed in a certain period of time is different with the distance of the honey source: if the distance is more than 1 meters from the nest, the figure-eight dance will be repeated within 15 seconds. Bees can only dance once at most. At the same time, the sweeter the nectar, the more times the abdomen swings when dancing. In this way, the worker bees who follow closely will know the distance and quality of the nectar source.
