1, the tail glows. The cells that can emit light under the epidermis contain fluorescein and luciferase. Fluorescein binds to substances containing energy. When there is oxygen, it is catalyzed by luciferase to produce light.
2. It can enlarge and narrow the light at will, or extinguish the light, which shows that it can control the oxygen supply of luminous cells.
Fireflies glow because of their special physiological structure. The ventral end of fireflies is filled with many phosphorus-containing luminescent substances and luminescent enzymes. Therefore, these phosphorus-containing luminescent substances and luminescent enzymes will emit faint light in the abdomen of fireflies, making them look like a small light bulb. Fireflies emit light not only for illumination, but also for signaling.
Fireflies belong to Insecta (Hexopoda), COLEOPTERA: Fireflies). The most unique feature of fireflies is that they have a special luminous body in their abdomen. The adults of fireflies are generally very small, most of them are 1 cm, and a few species can reach 3 cm. Female individuals are slightly larger than male individuals. Fireflies, like other insects, are divided into three parts: head, chest and abdomen.
Characteristics of life habits of fireflies;
Fireflies are carnivores and often prey on mollusks such as snails and slugs and annelids such as earthworms. After getting the prey, they inject the secretion into the prey with the upper jaw, digest it in vitro, and then inhale it. Usually a snail will have many fireflies to share. Eggs, larvae, pupae and adults can emit light, and the light of adults can attract the opposite sex.
