Firefly mine

1. Firefly is a kind of beneficial insect. 1. As a natural enemy, firefly larvae are important natural enemies of snails. Because the number of natural enemies of snails is extremely limited, and fireflies are more easily obtained than other kinds of natural enemies, firefly is the most promising biological control species of snails. 2. Firefly is an ornamental insect. 3. As an ecological indicator, firefly is very sensitive to environmental changes. The quantity of firefly can reflect the environmental quality of this area to a certain extent, and it is a kind of ecological indicator.

2. The common colors of fireflies are yellow, red and green. There are two sections on the abdomen of male fireflies, and only one section on the abdomen of female fireflies. Lighting is an energy consuming activity, which does not shine all night. Generally, it only lasts for 2 to 3 hours. The life span of alts is generally only 5 days to 2 weeks, which is mainly for mating and reproction. Firefly larvae are divided into aquatic and terrestrial. Larvae generally need six metamorphosis before entering the pupal stage

3. It doesn't matter if there are any advantages. If there are advantages, it's biodiversity, which makes people look good at night, or it makes lovers feel a little romantic.

firefly, also known as Noctiluca, Sem, Ruyi, yezhao, Liuying, Xiaozhu, Yaoye, etc., belongs to Coleoptera fireflies family, is a small beetle, because its tail can emit fluorescence, so it is called firefly. There are about 2000 species of this insect with luminous tail. The more common species in China are black firefly, red firefly and window chest firefly

the firefly is about 0.8 cm long, flat and slender, with a small head, soft body wall and Coleoptera, and its head is covered by a large chest plate. The antennae of the male are long, with 11 segments, flat filaments or serrated; In abdomen, there are 6-7 web segments, and there are luminaries at the end, which can emit fluorescence; Most males have wings. The female is wingless, larger than the male and unable to fly, but its fluorescence is brighter than the male

there are more than 2000 kinds of fireflies in the world, most of them appear in the riverside, pond side and farmland in summer, and their range of activities generally does not leave the water source

officially, glow worm is its larva, while firefly is its shining alt. Male firefly is more active and flies around to attract the opposite sex; The female stops on the leaves and waits for a signal. In the firefly, there is a kind of phosphide - luminescent substance. Through the action of luminescent enzyme, it will cause a series of chemical reactions. Only about 10% of its energy is converted into heat energy, and the rest is converted into light energy, which is called cold light

The light colors of common fireflies were yellow and green. Sometimes it is also red or orange red, the color is different because of the different three-dimensional structure of luciferase, which combines closely with the phosphor to emit green light, otherwise it is red or orange red fluorescence. The abdomen of male firefly has two nodes, and female firefly has only one node. Lighting is an energy consuming activity. It doesn't light up all night. Generally, it lasts only 2 to 3 hours. The life span of alts is generally only 5 days to 2 weeks, which is mainly for mating and reproction

5. Fireflies are active around 30 minutes after sunset, that is to say, fireflies can be seen after 7:30 p.m. in summer

catching fireflies usually adopts net bag method or bottle catching method

netting method is to use gauze netting to catch fireflies flying at low altitude at night. Because of its slow flight speed, it always gives out bright light, exposing its flight path very clearly, and flying at a very low altitude. As long as it is found and swept away with a net, it can be caught in nine cases out of ten. Sometimes the firefly is not caught, but the firefly will also fall on the ground and be caught by the sudden collision of the pocket net
for Fireflies resting in the grass or on the branches, hold the glass bottle with a large mouth, close to it, aim the mouth at it and gently wipe it into the bottle
if it stops at a low altitude, it can also be caught directly by hand. However, it should be noted that the insect is fragile and needs to be handled lightly, otherwise it will be pinched.

6. Firefly (English: Firefly), also known as Noctiluca, Sem, such as Yi Yi, ye Zhao, Liu Ying, Xiao Zhu, Yao Ye, etc., is a small beetle belonging to the Coleoptera family of fireflies. Because its tail can emit fluorescence, it is called firefly. There are about 2000 species of this insect with luminous tail. The more common species in China are black firefly, red firefly and window chest firefly
there are about 2000 species of fireflies in the world, which are distributed in tropical, subtropical and temperate regions. According to the statistics of several experts in China, there are more than 100 species found, and there are more than 150 species not found. It can be divided into aquatic and terrestrial species. They are small to medium-sized, long and flat, with soft body wall and Coleoptera. The anterior sternal plate is flat and often covers the head. The head is narrow. The eyes are semicircular. The eyes of males are usually larger than those of females. The abdomen is 7-8 segments, and there are luminaries below the end. The yellow green fluorescence is generated by the reaction of luciferin and luciferase in the body. When fireflies are nocturnal, their eggs, larvae and pupae can also emit light, and alts can attract the opposite sex. The larva preys on snails and small insects and likes to live in humid and warm places with abundant vegetation
therefore, it is only an insect.

A chemical called luciferase in fireflies interacts with oxygen to proce light. This chemical, known as luciferase, acts as a switch to start the reaction. When the firefly proces luciferase, it glows

There are about 2000 species of fireflies in the world, which are distributed in tropical, subtropical and temperate regions. The anterior sternal plate is flat and often covers the head. They like to live in humid and warm places with abundant vegetation

the head of firefly is narrow and semi spherical, and the eyes of male are usually larger than that of female. There are 7-8 segments in abdomen, and there are light-emitting organs under the end, which can emit yellow green light. The eggs, larvae and pupae of fireflies can also emit light, and the alts can attract the opposite sex. Firefly larvae feed on snails and small insects

Extended data:

< H2 >

the luminescence of firefly larvae is thought to have the function of warning and intimidating natural enemies, while alts are thought to use flash to identify species, courtship and trap. The male firefly emits a specific flash ring the flight, and the female firefly emits a response signal, by which the male firefly finds and locates the female firefly

the ration and interval of flashing of female fireflies are species-specific, so they can provide species information, gender information and location information to male fireflies. In the male competition of the same species of fireflies, the natural selection pressure makes the courtship ritual of male fireflies more and more complex and lasts longer and longer

female fireflies don't simply choose the male Firefly with the strongest flash brightness. The factors such as male size, moving speed and mating guard posture also determine the female firefly's choice of male firefly< br />

8. The principle of firefly luminescence
at night, people can see fireflies fly in twinkling. This is e to the interaction between a chemical substance called luciferase in fireflies and oxygen, which proces light. This chemical, called luciferase, acts as a switch to start the reaction. When the firefly proces luciferase, the reaction starts, and the firefly glows
there are many kinds of fireflies, and there is a luminous organ which can emit green light at the end of their abdomen. They lie in the grass ring the day and fly out at night. The small green light at the tail decorates the night sky like a dreamland. No wonder some people are scared. Not only alts, but also eggs, larvae and pupae can emit light. The alt has a light emitter at the end of its abdomen. The luminescent apparatus of male is two segments, and that of female is one segment. The transparent skin of the illuminator is provided with a luminous layer and a reflective layer. The luminescent layer is yellowish white, a protein luminescent substance called fluorescein. When fireflies breathe, the luciferin reacts with the absorbed oxygen to synthesize luciferase, and their tails start to glow
there are also algae in the ocean and other insects in the family fluoridae that can emit light by using insect luciferase to react with oxygen.

Larvae: the larvae of fireflies eat meat, while the larvae of terrestrial fireflies eat mostly smaller snails

alts: after metamorphosis into alts, most species of fireflies hardly eat or drink, and often only eat dew, honeydew or pollen or nectar; However, in South America, there are a few species of alt fireflies that glow and prey on other species of fireflies or small phototactic insects

There are about 2000 species of fireflies in the world, which are distributed in tropical, subtropical and temperate regions. According to the statistics of several experts in China, there are more than 100 species found, and there are more than 150 species not found. It can be divided into aquatic and terrestrial species

they are small to medium-sized, long and flat, with soft body wall and Coleoptera. The anterior sternal plate is flat and often covers the head. The head is narrow. The eyes are semicircular. The eyes of males are usually larger than those of females. The abdomen is 7-8 segments, and there are luminaries below the end. The yellow green fluorescence is generated by the reaction of luciferin and luciferase in the body

According to their living environment, fireflies can be divided into terrestrial and aquatic groups, the former being the majority. Terrestrial fireflies mostly live in places with high shelter, lush vegetation and high relative humidity, while Aquatic Fireflies have higher requirements on the environment. Water can not be polluted and light can not be polluted

10. Firefly is the only animal hard, firefly is the word "firefly" written wrong.
