Morphology

stone + fly

The compound is a direct noun+noun composition where 'stone' modifies 'fly', so a learner who knows 'stone' and 'fly' can plausibly infer an insect associated with stones or stony stream habitats. While specialized biological details (e.g. larval gills, taxonomy) are not predictable from the parts, the core sense—an insect found near stones/streams—is transparently derived from the constituents.

Etymology

Stone fly comes from the insect's young living under stones in fast streams and the grown insect that can fly. Fishermen often use them as 'bait', so the name links the stone-dwelling young and the flying adult and helps you remember a small insect found near water.
