Fireflies usually only appear in summer, so where do they go at other times?

Firefly Lampyridea is a general term for COLEOPTERA fireflies. There are about 2000 species in the world, distributed in tropical, subtropical and temperate regions. Fireflies are usually in the water except in summer, and will only emerge from the soil near summer.

About 54 species in China. Small to medium-sized, long and flat, with soft walls and coleopters. The back plate of the chest is flat and often covers the head. Small head. The eyes are hemispherical, and the eyes of males are often larger than those of females. The abdomen has 7 ~ 8 segments, and there is a luminous body below the end, which can emit yellow and green light.

Fireflies are active at night. Eggs, larvae and pupae often glow, and the glow of adults can attract the opposite sex. Both larvae and adults feed on snails and small insects, and like to live in humid and warm places with rich vegetation.

There is an apatite-luminescent substance in fireflies, which will cause a series of chemical reactions under the action of luminescent enzymes. Only about 65,438+0% of the energy it emits is converted into heat energy, and the rest is converted into light energy, which is called cold light. The light colors of common fireflies are yellow, red and green. The male firefly has two luminous segments in its abdomen, while the female has only 1.

Lighting is an energy-consuming activity, which doesn't shine all night, and generally lasts only 2 to 3 hours. Adult life span is generally only 5 days to 2 weeks, mainly for mating and reproduction of the next generation. Firefly larvae are divided into aquatic and terrestrial. Generally, it takes six metamorphosis to enter the pupa stage.

Larvae like to eat snails and crustaceans. After catching the prey, they will be anesthetized, and then the digested substances will be injected into the body to decompose the meat. In the grass, it is often found that the terrestrial firefly larvae glow at two points in the tail, and the two-color vertical-bearded firefly larvae emit black and white light. The wings of these two growing females have degenerated, which is not much different from the shape of larvae.

Only males can fly. On one occasion, some participants who lived near the farmland put female two-color fireflies with drooping beards in the window, attracting male two-color fireflies to wander around the window for several days, making the light weaker than common aquatic fireflies. In early spring, firefly larvae living in water will climb ashore and drill into the soil. At this time, gill breathing is changed to stomatal breathing.

The abdomen will glow. It takes about 50 days to become a pupa adult. There are only five days to live on average, and eating and growing will become secondary. After sunset, 1 hour, fireflies are very active, racing against time to chase each other. The male will blink for 20 seconds, wait for 20 seconds, signal again, and wait patiently for the strong response from the female.
