Beautiful scenery Shandong firefly water cave: a rare firefly spectacle in Asia

"Fireflies, hanging lanterns, flying from west to east ..."

Once upon a time, around June of the lunar calendar, fireflies with little stars often appeared in the countryside at night. Some naughty children grab them and put them in bottles to watch them shine, while others tear off the glowing parts and stick them on their foreheads or eyelids to "amuse".

It is said that there are nearly 2, species of this kind of insect with luminous tail all over the world, and the common ones in China are black firefly, red firefly and window-breasted firefly.

as for their origin, The Book of Rites? "The Moon Order" says: "The moon in summer and season ... rotten grass is firefly". Another "Theory of Gewu" said: "Fireflies are transformed from rotten grass and rotten bamboo roots." In fact, fireflies are grass roots that lay eggs at the water's edge, mostly lurking in the soil, and the grass pupates into adults the next year, which is fireflies.

It's hard to tell when fireflies gradually disappeared from the night sky in my hometown, just like the geese that used to fly south in autumn, but now they have disappeared.

"I've long hated the return of spring, and I don't know where to find it, so I've come here."
