CATDOLL : CATDOLL: How long can firefly larvae live? (How long can firefly larvae live?)

1. What do firefly larvae look like?

The lifespan of adult fireflies is not long, as short as three or four days, and no longer than two to three weeks. During this short period of time, they have to complete the mission of finding a mate and reproducing offspring.

Although the adult fireflies look quite good, their eggs and larvae are much inferior. A firefly goes through four stages in its life: egg, larva, pupa and adult. The eggs glow from the moment they are born, and they are faintly crystal clear, like a small version of a night pearl. The firefly larvae are fat, and after turning into pupae, they are covered with "armor".

There are light organs on the fifth and sixth abdominal segments of larvae, females and males, so it is easy to distinguish fireflies even in the twilight in the wild.

2. What are the conditions for breeding fireflies?

The feeding device can be a wire cage or a glass bottle, but be sure to leave ventilation holes. You can also use a transparent plastic box, but also be sure to leave ventilation holes. It is best to use iron gauze as a cover. This kind of insect will not fight or bite each other, so multiple insects can be raised together. You can put some young locust leaves or freshly picked grass in the bottle, and cover the bottle mouth with plastic gauze, iron gauze or gauze. It is advisable to maintain a certain humidity in the bottle. You can sprinkle a little water every day, and spray some water before feeding the young grass or locust leaves.

After fireflies transform into adults, most species of fireflies hardly eat or drink, and often only eat dew, honeydew or pollen and nectar. In South America, a few species of firefly adults will glow and prey on other types of fireflies or small phototactic insects as food.

Firefly habits:

1. Fireflies love to eat the body fluids of snails. You can catch 1-2 live snails every 2-3 days and put them in the feeder for them to eat. If the feeder is a glass bottle or a transparent plastic box, you can observe them eating snails.

2. If you raise 10 to 25 fireflies in a bottle, you only need to provide 1 snail each time. If you raise more than 25 fireflies, you can put 2 snails each time. Fireflies can generally be raised for 15 to 20 days, and if they are well raised, they can live for 1 month.

3. Firefly larvae are terrestrial species, so they should be covered with fine nets to prevent them from escaping; a vegetable garden can be planted to raise snails for the larvae to prey on. For aquatic species, artificial rivers can be built to allow the water to circulate, and it would be best if there were artificial waterfalls to increase the amount of oxygen dissolved naturally.

3. How long does a firefly live before it dies? How long is its life cycle? What is its living environment like?

There are more than 2,000 species of fireflies in the world. They appear by rivers, ponds, and farmlands in summer, and their range of activities generally does not leave clean water sources. Officially speaking, glow-worm refers to its larvae, while firefly refers to the shining adult fireflies. Male fireflies are more active and actively fly around to attract the opposite sex; females stay on leaves and wait for signals. There is a phosphide in the firefly's body - luminescent substance. After the action of luminescent enzymes, it will cause a series of chemical reactions. Only about 10% of the energy it emits is converted into heat energy, and the rest is mostly converted into light energy. Its light is called cold light. Common firefly light colors are yellow, red and green. Male fireflies have two glowing segments on their abdomens, while females have only one segment. Lighting up is an energy-consuming activity and will not light up all night, usually only for 2 to 3 hours. The lifespan of adults is generally only 5 days to 2 weeks, and this period is mainly for mating and reproducing the next generation. Firefly larvae are divided into aquatic and terrestrial. Larvae generally need to metamorphose 6 times before entering the pupal stage. The larvae like to eat snails and crustaceans. After catching prey, they will first anesthetize it and then inject digestive substances into its body to decompose the meat. The terrestrial mountain window firefly larvae with two glowing spots on the tail and the bicolor drooping whiskers larvae with glowing black and white stripes on the whole body are often found in the grass. The wings of the grown female fireflies of these two species are degenerate and the shape is not much different from that of the larvae. Only male fireflies can fly. Once a participant who lived near a farmland placed a female bicolor drooping whiskers firefly on the window, and attracted male bicolor drooping whiskers to wander around the window for several consecutive days. The light emitted was weaker than that of the common aquatic fireflies. In early spring, firefly larvae living in the water will crawl onto the shore and burrow into the soil. At this time, they breathe through gills instead of spiracles. Both sides of their abdomen will glow. It will take about 50 days to turn into pupae and adults. They only live for an average of 5 days, and eating and growth become secondary. One hour after sunset, fireflies are very active and compete for time to pursue each other. The male will flash a bright light for 20 seconds, wait 20 seconds, and then send out a signal again, patiently waiting for the female to respond with a strong light. If there is no response, the male will fly away. (This phenomenon needs to be observed) Fireflies only start to glow when it is dark. Participants should use flashlights to light the way, and avoid shining directly on the haystacks. Fireflies may stop glowing for a short time when illuminated by flashlights, and you can't find them. In the Jin Dynasty, there was a poor student named Che Yin. In order to save money on oil for lighting lamps every summer, he caught many fireflies and put them in a porous bag, and used the firefly light to read. He was finally appointed as the Minister of Personnel. From today's point of view, Che Yin must have been a serious myopic in his youth.

There is a kind of "fluorescent mushroom" in Taiwan that glows in the dark. Lantern flies have glowing insects parasitic in their bodies, so they can also glow at night.

There is a kind of "fluorescent mushroom" in Taiwan that emits fluorescence in the dark. There are more than 2,000 species of fireflies in the world.

4. How long is the lifespan of a firefly?

Fireflies generally live 3-7 days in the wild, and a few live 10-20 days, which shows that the life span of fireflies is very short. When fireflies larvae become adults, they no longer hunt, but live on dew or nectar, and eventually starve to death.

5. Can fireflies only survive one night?

No. The life cycle of a firefly is usually one year, with the egg and larval stages accounting for most of its entire life cycle, while the adult stage is often only about 1 month. Except for a few diurnal fireflies, most fireflies have a milky white light organ at the end of their abdomen. The luciferin in the body reacts with oxygen through a biochemical reaction with the participation of luciferase to emit fluorescence. Common firefly light colors are yellow, red and green. Although fireflies are very efficient in luminescence, they still consume their own energy, so they usually do not glow all night. Adult fireflies glow for 2-3 hours every night, while larvae glow for a slightly longer time. Firefly larvae are carnivorous insects that can feed on freshwater snails, snails or other insects; adult fireflies only feed on small amounts of pollen and dew.

6. How long can adult fireflies raised in captivity live?

Fireflies spend most of their time in the larval stage, which lasts from half a year to a year. The lifespan of an adult firefly is only 3-5 days.

Fireflies are also known as "night lights" and "flowing fireflies". They are named fireflies because their tails emit fluorescence. Fireflies like to live near water or in humid environments and are usually active at night. The eggs, larvae, pupae and adults of fireflies can all glow, and the glow of adults can attract the opposite sex.

Fireflies are afraid of light. They glow at night to seek mates and reproduce. However, the bright lights in the city seriously interfere with the fireflies' courtship behavior. The life cycle of an adult firefly is only 3-5 days. Once it is disturbed by light, it cannot normally seek mates and reproduce, and eventually it can only die silently.
