The magical “biological antenna”

  Insects, arthropods and some mollusks have long whiskers on their heads, which are called “tentacles” in biology. Scientists have discovered that the communication ability of insects is closely related to the shape, size and structure of their antennae.
  Antennae like “antenna”
  research has found that the length of the felt hair on the antennae of insects is related to the wavelength of electromagnetic waves, and what they receive has the ability to receive weak infrared rays. Infrared is a kind of electromagnetic wave, the antennae of insect may be a kind of receiving antenna for weak electromagnetic wave, and the felt hair on the antennae of insect is a resonator that can resonate infrared.
  There are many types of tentacles, with multiple tentacles having lengths and shorts. The general length is one-quarter to one-half of the body length. But there are exceptions. The antennae of longhorn beetles and weavers exceed their body length, and the antennae of zebra horses are more than five times their body length.
  Different insect species have different tentacles. The antennae of a butterfly are cylindrical; the antennae of a male moth resemble feathers; the antennae of a beetle are stacked like fish gills; the first and two segments of the base of the antennae of a dragonfly are thicker, and the remaining segments become thinner as they are closer to the tip; The base of the antennae is extremely long, and the other segments are bent aside, shaped like a bent knee; the antennae of the click beetle looks like a saw, and each segment is triangular; the top corners of the antennae of the Guo Gong insect are enlarged. Hammer-shaped.
  Magical reach
  different types of antennae, its function is not exactly the same. In addition to the common functions equivalent to the “nose”, some antennae also have the function of “ears” and other functions.
  There are more than 3,600 olfactories distributed on one antenna of a bee. There are many nerve endings connected to the cranial nerves inside each olfactory organ, which makes its sense of smell particularly sensitive.
  Ants can secrete a chemical substance for “verbal communication”. They use their antennae as “antennas”. When the antennae of two ants are in contact, they can send out a kind of “code” to talk to each other and exchange information.
  The sound produced by a female mosquito flapping its wings has a fixed frequency. The male mosquito uses its antennae to feel the sound. Its antennae will resonate with the sound of a female mosquito of the same type at a specific frequency, allowing it to quickly find a favorite partner.
  When cockroaches are active at night, they will swiftly and quickly run away when they hear slight footsteps or see lights. Scientists have discovered through experiments that its antennae belong to the most sensitive level, and will generate signals for movements of extremely small distances. Finding food depends entirely on its sense of smell. If you cut off the two antennae of a cockroach, it will starve to death because it cannot find food.
  The head of a snail is well-developed with two pairs of antennae, one pair of eyes grows on top of one of the large antennae; the other pair of small antennae are its olfactory organs.
  The snail has a pair of antennae on its head. The male’s right antennae is curved, while the female’s right antennae is straight. Why are their left and right antennae different? It turns out that the snail is a dioecious shellfish. Since there is no special copulation organ, the right antennae of the male snail can transport sperm.
  The tentacles of male mosquitoes are particularly developed, with both smell and hearing functions. There are ring-shaped bristles on the antennae, and “direction finding” organs at the base. When the female mosquito hums at a frequency of 350 to 5000 Hz, the sound waves push the bristles on the antennae of the male mosquito, and the “receptors” perceive the frequency of the female mosquito’s sound waves, and the male mosquito can determine the position of the female mosquito. Busy to find lovers.
  People must think that when nocturnal insects fly at night, their eyes must be very good, but in fact they are not. Their eyes are just a decoration, they can’t see obstacles at all. It turned out that the tentacles helped them a lot! There are a lot of sensory hairs on their antennae, which can feel the pressure of the airflow, so that they can avoid obstacles. The sensitive sensation of insects is more advanced than modern radar detection systems.
