Morphology
sow + bug
The modifier 'sow' in 'sow bug' is not the transparent, compositional element a B1 learner would expect (it is not a clear locative or descriptive term like 'wood'), and the compound is a lexicalized name for a specific crustacean. Knowing common senses of 'sow' (female pig or to plant) plus 'bug' would not allow a learner to infer 'small terrestrial isopod', so the meaning is unpredictable from the parts. Cross-linguistically many languages use different, more transparent names (e.g. 'woodlouse'), which signals this is an idiomatic/common name rather than a compositional phrase.
Etymology
Sow bug may come from farmers who thought the little animal acted like a sow, a female pig, because it was often found looking for food in damp soil and garden beds. That simple image of a 'pig-like' bug helped the name stick, so today sow bug means the small ground creature you find under stones.
