Switching to energy efficient, overly bright LEDs is not helping, said Owens. Many fireflies rely on bioluminescence – chemical reactions inside their bodies that allows them to light up – to find and attract mates, and too much artificial light can interfere with this courtship.

But scientists say this magical display is under threat – with the loss of their natural habitats, pesticide use and artificial light putting some of the 2,000 or so species at risk of extinction. Around the world, fireflies light up the night with their shimmering bodies. ![]()
