How it's used
While 放光蟲 is a descriptive term for any light emitting insect, it is most commonly used by children or in casual conversation to refer to fireflies. The more standard or scientific name for a firefly is 螢火蟲, which is used in formal writing and by adults. Using 放光蟲 adds a sense of wonder or simplicity, as if describing the creature by its most magical feature.
