Morphology

caddisfly = caddis + fly (semi-transparent) = caddis + fly

The compound clearly combines 'caddis' + 'fly', but 'caddis' is an infrequent, specialized term so many learners will not be able to infer the meaning.

Etymology

Caddisfly probably comes from an old word caddis meaning 'case' or 'pouch', because the larvae make small protective cases from sand, stones, or plant pieces. So thinking of a caddisfly as an insect that carries a tiny 'case' helps explain its name.
