Meaning and background
The story behind Firefly
Firefly has a precise natural-history association: the dictionary identifies light-producing nocturnal beetles, especially in the Lampyridae family. The name's fly ending does not make the insect a true fly in that definition. A dog owner may choose Firefly for the image of intermittent light or a particular outdoor memory. That is a documented animal-word association, while any film or television reference would need its own source rather than being assumed.
