Larvae, or young moths, will also eat paper, dust, and materials covered in oil. Clothes moths are also known to infest deceased insects, hair, and animal remnants that have dried out.

Fireflies eat other fireflies. Fireflies are primarily carnivorous. Larvae usually eat snails and worms.

But adult fireflies have almost never been seen feeding on other species of bugs.
