but light
Most beetles do not produce light, but a few species do. Most notable are fireflies.
There are fireflies... and ants.. and bears
The light produced by fireflies is bright enough that you can see them from at least a hundred if not more than two hundred feet away. However, they don't make enough light to brighten a room or come close to comparing with a light bulb. Also, they can only make short spurts of light at a time.
Luciferin is a compound that gives the fireflies, and any organism that has it, its light.
