Fireflies are released into the air at a nighttime event in Chengdu City, the capital of Southwest China’s Sichuan Province, June 25, 2016. Organizers said about 100,000 fireflies were set free in the event that attracted a large number of visitors. But Zhao Li, curator of the Insect Museum of West China, was strongly against the activity, noting they will all die in three days to a week because the insects have high environmental requirements to survive.
