Tourists date fireflies in Xishuangbanna

“Lightning fireflies would gather around ponds and wetlands when the sky turns dark, but gradually cease flashing after 9pm,” explained a staff.

The garden suggested tourists not to use a torch or camera flash to light up the area where fireflies congregate.
