What are the lightning bug's favorite foods?

Adult lightning bugs, or fireflies, usually live on nectar or pollen, although some species do not eat once they have reached adulthood. Firefly larvae typically eat worms and slugs. The larvae numb their prey by injecting it with special digestive fluids.

There are about 2,000 species of lightning bugs. They are found all over the world, except in the very coldest northern and southern regions. Fireflies prefer humid or damp areas.

Fireflies have special abdominal organs that combine the compound luciferin with oxygen to create their signature flashes of light. Each species of lightning bug emits its own pattern of flashes, which are used to help locate mates.
