Firefly generally refers to the order coleoptera, a number of which has been recorded in the world over 2000, distributed in temperate, subtropical, and tropical regions. Fireflies belong to completely metamorphotic insects, and undergo four stages of egg-larva-pupa-imago in life, which are divided into terrestrial and aquatic categories. The living environment of terrestrial fireflies is not limited by the region of the water environment, but is closely related to environmental factors such as environmental humidity, vegetation coverage rate, sunlight visibility and the like. Each insect state of the aquatic firefly water has different ecological niches; the larvae grow in water, the pupal stage passes through the revetment soil, and the imagoes inhabit and eggs are laid in the plants on the revetment side. Fireflies are very sensitive to changes in the ecological environment, especially water pollution and light pollution, and thus can serve as environmental indicator species.
In recent years, the environment of firefly habitat deteriorates rapidly due to factors such as rapid economic development, accelerated urbanization, and environmental pollution, and the species and population number of fireflies down rapidly, thus posing a danger of extinction.
