Fireflies are non-dragon creatures. They are small insects which produce light and can easily be spotted at night. Females are about 2 cm big, males only 1.5 cm. The larvae eat mollusks and thus are considered carnivores, while the adults eat nothing and only live a few weeks to mate. Fireflies are also the main diet of Dusk Dragons. Fireflies are stated in legend to have allowed the creation of the Dawn Dragon.
