I saw fireflies yesterday, flying at night, and even while they were mating, so I thought I'd share some of the magic I saw :).
It has become a tradition now for my friend Joep and I: around the end of June we search for fireflies during a hike in the dark. The specific lightning bug species that lives in my area is the Lampyris Noctiluca; also known as the common glow worm of Europe.
The male fireflies of this species are tiny and can fly, while the females cannot: she's a larviforme, much bigger than the male (with a shinier butt!). Below you can see a GIF from the video of the male and female Lampyris Noctiluca.
After mating, the fireflies die. The ones in this video we found in Sweikhuizen and Beek in the south of the The Netherlands.
