What does "moth to the fire" stand for?

"Moth to the fire", the zodiac is a snake.

Snakes are a kind of reptiles.

The snake is a kind of temperature-changing animal whose body temperature changes with the temperature, because the snake itself has no perfect temperature regulation mechanism to generate and maintain a constant body temperature. The optimum temperature for snake activity is 20-30℃. In this suitable range, the growth rate of snakes increases linearly with the increase of temperature. Air humidity also has a great influence on snakes, generally 50 to 70% is appropriate. The activities of snakes are closely related to the external temperature, humidity, light and food. Under the influence of these external environmental conditions, there are obvious seasonal and daily changes.

seasonal

In most parts of China, the temperature changes greatly throughout the year, so there are obvious seasonal differences in snake activities. Generally, from late spring to early summer to early winter, the temperature is 10 to 35℃, which is suitable for snake activities. It has been observed that at 20-35℃, snakes will forage, drink or bathe everywhere.

In winter, when the temperature starts to drop and get cold, the snake's body temperature will drop and its function will also drop. When the temperature drops to 10℃, the snake stops all activities and begins to hibernate. During hibernation, snakes do not eat or drink, and their metabolism is minimized. They rely on the accumulated fat in their bodies to provide energy and maintain the minimum needs of life activities. Hibernation is the adaptation of snakes to low temperature, and it is also a long-term genetic feature of snakes. When hibernating in the wild, dozens or hundreds of snakes often gather in dry caves and tree holes, which can raise body temperature and reduce water evaporation, which is conducive to wintering. It was not until the following spring that the outside temperature was higher than 10℃ that the snake woke up from hibernation and began to live out of the hole.

When the temperature is higher than 35℃ in summer, the snake's body temperature rises. At this time, the snake's activity is reduced, and at the same time, it will hide under the big tree, by the pool, in a cool and humid place to lower its body temperature and not die of heat. In addition, whenever the weather is hot in summer, snakes living in dry deserts and snakes living in tropical and subtropical areas will hide in wet places under the shade of trees and sleep motionless in summer. Summer sleep, like hibernation, is also a genetic feature of snakes adapting to the environment.

Physiological rhythm

Circadian rhythm refers to the daily activity law of snakes, which is related to foraging, environment, temperature and light. Generally speaking, king cobra and cobra mainly feed during the day and rest at night, which is called daytime activity. Bungarus multicinctus and Bungarus multicinctus mainly go out for food at night, which is called nocturnal activity. However, Agkistrodon halys often go out for food in the morning and evening, which is called morning and evening activities. Generally speaking, the law of day and night activities depends largely on the activity time of animals preyed by snakes.

In addition, the activity of snakes is also related to the external humidity. Such as Agkistrodon acutus, welding head, bamboo leaf green, etc., are active in rainy days with high humidity and are extremely active. Cobra, etc. Most of them go out on sunny days with low humidity. Generally, when it is about to rain or cloudy for a long time, the weather is sultry and the humidity is high, the snake will take the initiative to go out. Most snakes go out during the day or at night for food. Whenever they have a full meal, they will sleep in their habitat for a few days, and then go out to look for food after eating the food in their stomachs.
