CATDOLL : CATDOLL:How many eyes do bees have?

1. How many eyes do bees have?

Bees have a pair of compound eyes and three simple eyes.

The compound eyes of bees are not simple, they are made up of thousands of small eyes. In fact, the compound eyes of bees are not completely the same. The compound eyes of bees grow on both sides of the head, but among the three types of bees, the compound eyes of drones are larger and connected, while the compound eyes of worker bees and queen bees are smaller and separate.

The compound eyes of bees cannot rotate like human eyes, but the thousands of small eyes in the compound eyes of bees can move in different directions. It can be said that although the compound eyes of bees cannot rotate, the field of vision is very large. The compound eyes are mainly used to see objects at a distance, and can judge the location, color and shape of flowers when collecting nectar.

Bees have three simple eyes, each of which is independent and located in the center of the bee's head, between the two compound eyes, forming a triangle shape. The function of the simple eye is night vision.

The simple eye of a bee can clearly sense the intensity of light, so it comes in handy when viewing objects at close range. For example, the bee relies on the simple eye to complete its work at night, and the simple eye of the bee can also assist the work of the compound eye.

Additional information:

Honey bees have pronotum that does not reach the wing base, and their bodies are covered with branched or feathery hairs. Their hind legs are often specialized for collecting pollen. The adult body is covered with velvet hairs, and the legs or abdomen have pollen collecting organs composed of long hairs. The mouthparts are chewing and sucking, which is a unique feature among insects. They are called resource insects.

The adult bee is about 2 cm to 4 cm long. The queen bee lays eggs in the hive, and the larvae live in the hive. The larvae that live a social life are fed by the worker bees, and the larvae that live a solitary life eat the bee food stored in the hive by the female bees. When the bee food is eaten up, the larvae mature and pupate, and then emerge from the cocoon. Domestic bees breed several generations a year, while wild bees breed 1 to 3 generations a year. They overwinter as mature larvae, pupae or adults.

Males usually appear earlier than females, have a shorter lifespan, and do not build nests, store bee food, or raise offspring. Female bees build nests, collect pollen and nectar, and store them in the nest chamber, and have a longer lifespan than males.

In addition to a pair of compound eyes, bees also have three simple eyes, which are arranged in a triangle with the two compound eyes to sense changes in light intensity and the direction of the light source, forming a rough image. A bee's eyes are composed of about 5,000 ommatidia, each of which has a light-collecting system and a light-sensing system. The light-collecting system can form an image, and only light parallel to the axis of the ommatidia can reach the visual column, which means that each visual column can only receive one light point of the object, and the many light points sensed form a "mosaic image", just like many light points of different brightness and darkness form an image on a television screen. The more ommatidia there are, the smaller the ommatidia area, the denser the light points sensed, and the clearer the image.

The eyes of bees are called visual organs: they are composed of a pair of compound eyes and three simple eyes. The compound eyes are composed of several digital sensory units (ommatidia). Each ommatidia in the compound eyes is composed of 8 photoreceptor cells arranged in a radial pattern.

Each compound eye of a worker bee has about 5,000 ommatidia, each compound eye of a queen bee has about 4,000 ommatidia, and each compound eye of a drone has about 8,000 ommatidia.

2 compound eyes and 3 simple eyes, a total of 5 eyes.

2 eyes

5. What do bees use to make sounds?

In the fall of 2001, Nie Li learned from the book "Tutorial on Nature Study in Primary Schools" that insects such as bees, flies, and mosquitoes are dumb. They have no vocal organs, but they have wings that can make noises. When flying, these insects flap their wings at high speed, causing the air to vibrate, thus producing a buzzing sound. Later, Nie Li also saw in "One Hundred Thousand Whys" that the buzzing sound of bees comes from the vibration of their wings, up to 200 times per second. If the wings stop vibrating, the sound will stop. She asked her teacher for confirmation, and the teacher's view was the same as in the book.

Last spring, Nie Li went to a bee farm and found that many bees gathered on the beehive. They did not flap their wings, but they still buzzed non-stop. So she questioned the textbooks, popular science books and the teacher's explanations, and began to experiment and study bees. She first glued the bee's wings to a wooden board with glue, and the bees still made sounds. She cut off the bee's wings and could also hear the bees' calls. The two methods were repeated 42 times, using 48 bees each time. The experimental results showed that bees can make sounds without vibrating their wings. In order to explore the bee's vocal organs, she glued the bees to a wooden board and carefully searched with a magnifying glass. After observing for more than a month, she finally found two black spots smaller than rapeseed at the base of the bee's wings. When the bee called, the black spots moved up and down. She poked the small black spots with a pin, and the bees stopped making sounds. She found some more bees, did not damage their wings, but only pierced the small black spots, and put them in the mosquito net. The bees flew around and there was no sound. She repeated this experiment 10 times, and the results were the same. She wrote a paper about her discovery, concluding that the bees' vocal organs are these two small black dots.

It is reported that Nie Li's paper has been included in the collection of award-winning works by the competition organizing committee, and the journal of the Chinese Education Association and the Primary School Natural Science Teaching Professional Committee has also published the full text of Nie Li's paper.
