Tiny fireflies.
There are 4 stages of egg, larva, pupal and adult in a lifetime, and each stage can shine, which can be described as a "shining life". They tend to be born from generation to year and have a lifespan of only one year at most. In a short life, they first go through an egg stage of about 20 days, then a larval stage of about 10 months, and then an adult worm after pupation in 7 days, enjoying the last and brightest 7 to 10 days of life.
Fireflies have a luminescent apparatus at the back of their body, which is made up of thousands of cells that emit light with two luminescent substances, fluorescein.
and luciferase. Luciferin, luciferase, and adenosine triphosphate.
binding, under the action of oxygen, emits fluorescence. For firefly larvae, the glow is used for warning and defense, but for adults, the meaning of glow is to fall in love.
These adults have no hearing, and the rhythm of their glow is their language. Different species of fireflies have completely different luminescence rhythms, so there is no possibility of "hybridization". After a male and a female of the same species, the male will fly into the grass alone, mate with other females of the same species 2 to 3 times, and die of exhaustion.
And the female worm also came to the end of her life after completing the big task of "laying eggs". In fact, out of 200 to 300 eggs laid by females, only 2 to 3 survive.
Fireflies are divided into two categories: terrestrial and aquatic, with the former being the majority. Terrestrial fireflies mostly inhabit places with lush vegetation and relatively humid areas, while aquatic fireflies have higher environmental requirements and cannot be polluted by water.
There can also be no light pollution. They also travel regularly. Most fireflies recuperate in the grass during the day and shine at nightfall.

The most active season is summer.
Summer is the season for fireflies to breed, and it is a sight to see thousands of fireflies flying along the river in the summer.
In terms of the lifespan of several decades for human beings, the life of a firefly may face death after this time.

During the summer months, fireflies appear in the evening or at night in June and July. Most species start their activity after sunset, and most of them stop at 8 p.m. or 9 p.m. Firefly larvae appear at night for about the same time as adults, but they can be active all night.

Hello, actually, the most active season for fireflies is in the summer of each year. In the summer evenings of each year, if we go to some of the darker places in this kind of meadow, it may be easy to find fireflies, of course, provided that there are no polluted places, because fireflies they like to live in some green environment.

Fireflies are the most active.
It's summer.

Fireflies prefer hot and humid summers, most often in June, July and August, and fields and small rivers, especially where there is water, are their happy gathering places. Therefore, the summer season is the most active, and June, July and August are the most active seasons for fireflies.
At night, in the fields and small rivers, especially where there is water, you can often see a group of fireflies enjoying this beautiful night, they have cells that can emit light, and synthesize fluorescein, which is the secret of luminescence.

My favorite is to stay quietly alone on a summer night, my grandfather's house is in the countryside, there is a small river flowing in front of the house, there are clumps of green four-leaf clovers growing by the river, the breeze blows, as the wind bends down to salute the comers, and a small white bridge crosses the river, connecting the two villages. My grandfather loved me very much, and in order to make me happy, he put a swing in the yard and decorated it with four-leaf clover, facing the river in front of the door.
On summer nights, swarms of fireflies often appear by the rural riverside, flashing and flashing on the quiet summer night, as if waiting for the late returnee. The four-leaf clover by the river exudes a fresh scent. Naughty, I called my grandfather, brought a useless cloth, and secretly stood by the river, catching fireflies one by one, sometimes I couldn't catch them and threw myself on my stomach, but I smelled the fragrance of the earth.
After catching the fireflies, I folded the cloth at the four corners, leaving a place that looked like water droplets to put the fireflies. Soon, the cloth bag lit up, I held them like a child during the Spring Festival with a lantern to play, after a while, the "lantern" was extinguished, I was surprised, called my family loudly, the family told me that the life of fireflies is very short, short to only one night of light. I don't know what it's like.
Later, I figured it out: the reason why fireflies release their brilliance at night is because they know that life is fleeting, and even if Yan Heng knows that he can't escape the doom of death, he must bloom to the fullest.
At that moment, the spring warmth of my world was like a flower, because it made me understand that life is as short as its life, but people should be as gorgeous as it is when they live.
