In the insect world, insects that can fluoresce at the tail are generally referred to as fireflies, and there are many types of fireflies, there are about 2,000 kinds of fireflies in the world, and different fireflies have different characteristics. Recently, in Chengdu Qionglai Tiantai Mountain Scenic Area, there are staff found a peculiar firefly - female fluorescent fireflies, the shape of a caterpillar, the whole body has more than 30 glowing points, this firefly is relatively rare.
According to reports: Tiantai Mountain Scenic Area has found more than 20 kinds of fireflies, this female fluorescent shape is spindle-shaped, body length of about 8 cm, body width of about 1.3 cm, the whole body of the luminous point is very symmetrical, there are about 30 luminous points, found that this female fluorescent firefly is very meaningful, and added a new member of the firefly family of Tiantai Mountain.
In the fireflies, the female fireflies have a relatively large difference in the appearance of the male and female, the female female of the female fireflies is yellow worm-like, the male is black and has front and rear wings, which is also the characteristic of many fireflies species, most of the males have wings, the females are generally wingless, no ability to fly, but the females are larger than the males, and the fluorescence emitted is brighter than the males.
Fireflies emit light, on the one hand, to intimidate predators, with protective warning effect, the second is to use flash for identification, courtship and trapping and other activities, so fireflies will continue to fluoresce, and the principle of their fluorescence is: fireflies have special light-emitting cells, and the main substances in the light-emitting cells are fluorescein and luciferase, in the process of light-emitting, fluorescein will be consumed, and fireflies will continue to replenish energy.
In the animal world, fireflies are not only good-looking, but also a beneficial insect, fireflies effectively prey on agricultural pests, such as snails, slugs and other mollusks, but also prey on horse land, earthworms and other link animals, has a unique role in ecology.
Fireflies have a wide variety of species, the number of populations is also relatively large, the distribution is very wide, but in recent years due to habitat loss, artificial light, excessive use of pesticides, etc. have caused great threats to the firefly population, especially some fireflies species can only survive in a specific environment, so there are fireflies experts have shown that many of the more than 2,000 kinds of fireflies known worldwide are facing extinction.
Pay attention to the six dimensions of nature And let nature know nature!
