Morphology

lightning + bug

The compound combines 'lightning' (a bright, flashing natural light) with 'bug' (an insect), so a learner who knows both words can plausibly infer it refers to an insect that produces light (i.e. a firefly). This is a straightforward descriptive composition and parallels cross-linguistic names for luminous insects, making the meaning readily derivable for a B1 learner.

Etymology

Lightning bug comes from the tiny insect's bright flashes at night. People saw a little bug that flashed like lightning, so the name means 'firefly'.
