Morphology

caddis + fly

The compound is a straightforward noun-noun composition: 'caddis' (a specific aquatic moth/larval type) + 'fly' (a small insect) yields an insect of the caddis type. This follows common English naming patterns for animals, so a B1 learner who knows both constituents can derive the meaning.

Etymology

Caddis fly may come from an old word for 'coat' or 'cover'. Young caddis build little cases from sand and plant bits and live inside them underwater, so the name fits an insect that is 'covered' in a tiny home.
