For ten days in the summer, the forests of Japan’s Yamagata prefecture are lit up by hime hotaru, a type of firefly endemic to the region.
Photographer Kazuaki Koseki has attempted to capture the phenomenon in his Summer Faeries series, compiled over a period of eight years. “The spectacle of fireflies flying through the summer forest is like the twinkling of a starry sky,” says Koseki.
“That sight is fantastic enough to forget the awe of the night forest.” In recent years, the fireflies’ habitat has been increasingly endangered by deforestation and the tourism industry.

A friend took me to see 'em. You took a boat and the big bushes on either side were full of fireflies. The kind of trigger each other so you have these waves going round and round all reflected in the water. Very cool. Wonder if someone has video'd them... nah, the vids all suck

Oddly, cats can't see them.
Or don't chase them.
They have an odd colour which I suspect cats can't see in the dark.
