Summer days as children, the impatient sound of cicadas during the day and the crisp frog song at night are the constant themes of hot summer. At that time, everyone liked to cool off in the evening breeze! Adults are idle, and children are running around. Catching glowing fireflies is one of the joys of a child!
Yellow-rimmed short-angle window fireflies
There are many kinds of fireflies, about 2,000 species in the world and more than a hundred in China. There is a certain distribution in all parts of China, but the southern and southeast coastal distribution is mostly. The more common ones in China are black fireflies, ji red fireflies, window chest fireflies, etc.
Black-winged fireflies
Fireflies appear in the hot summer, according to the habits of fireflies, every day is usually between the time when the sun has just set and the evening, generally speaking, about 7 to 9 o'clock is the most active time for fireflies, after nine o'clock, most fireflies find a mate and start mating. It mostly lives in the shade of damp trees or grass, and flies at low altitude at night.
Yellow-veined winged fireflies
Fireflies can emit light because the end of the firefly's abdomen is filled with many phosphorus-containing luminous substances and luminescent enzymes, and these phosphorus-containing luminous substances and luminescent enzymes emit a faint flash of light in the abdomen of the fireflies. The bright light emitted by fireflies is mainly to send signals, and fireflies use this way in courtship, vigilance, trapping, etc.
Fireflies have very high requirements for the living environment, but due to excessive rural land reclamation and the large use of pesticides and fertilizers, the living space of fireflies is becoming less and less, and the environment is getting worse and worse. So there are fewer and fewer fireflies!
Life is getting better and better now, but the environment is getting worse and worse! When she was a child, I heard my grandmother tell her that when she was young, she could often see large flocks of wild ducks flying overhead, and porpoises could be seen in the river next to her home. Now don't talk about wild ducks, there are many fewer sparrows! I hope that the country will not only have gold mountains and silver mountains, but also green mountains and green waters.
