The lamprey family belongs to Arthropoda, Xiachin, Insecta, Araneae, Coleoptera and Polypoda, belonging to Mylabridae, and the other two families are red fireflies.
Fireflies are commonly known as "fireflies" and are also called "fireflies" in Cantonese. About 2000 species are known in the world, distributed in tropical, subtropical and temperate regions.
Extended data
The color of light emitted by fireflies is determined by the structure of fluorescein in its body and the interaction between fluorescein and luciferase. Fluorescence spectra are species-specific, and the spectra of different fireflies are different.
Most fireflies emit yellow-green fluorescence, and the information contained in yellow-green light at night is easily received by similar fireflies. In signal transmission, yellow and green light can reduce the loss as much as possible to improve the efficiency of signal reception, that is, signal-to-noise ratio.
Fireflies like to live near the water or in humid environment, and usually move at night.
Carnivorous, preying on mollusks such as snails and slugs, and annelids such as earthworms. After the prey is obtained, the secretion is injected into the prey with the upper jaw, digested in vitro, and then inhaled. Usually a snail will have many fireflies to share.
