Headlamp beetles are part of the click beetle family but they are click beetles with a difference - two spots on their body that glow in the dark like car headlights! The two glowing spots on the back of their body occur due to enzymes that create light - something known as bioluminescence. Scientists think they use these lights to attract a mate. However, the enzymes also produce an orange light on the underside of their body that glows as they prepare to take off, much to the amusement of insect expert Dr George McGavin.
