Fireflies are the "little elves" of summer nights. Every year in June, they start to be active, reach their peak in early July, and remain active until September.
In previous years, fireflies can only be seen in the suburbs of Qingpu and Fengxian in Shanghai, but this year they can also be found in some parks in downtown Shanghai.
Fireflies are sensitive to light and noise, and have high requirements for water sources and vegetation, and can only survive in places where the environment is suitable. Therefore, the large number of fireflies can be seen as a sign of ecological environmental improvement.
Xinjiangwan Wetland Ecological Bird Watching Bird Shooting Base is an area where a large number of fireflies can be observed in downtown Shanghai. As soon as the Knews reporter entered the wetland, he found a dotted firefly in the grass near the river. After dinner time, many citizens will bring their children here to look for fireflies, and some of them are seeing this magical creature that shines for the first time.
The lifespan of adult fireflies in the wild is generally 3 to 7 days, and the longest is only 10 days. In their short lives, they use a little glimmer to complete the mission of finding companions, courtship, and reproducing offspring.
