Morphology

wheel + bug

The compound 'wheel bug' is a straightforward noun+noun construction where 'wheel' describes a salient feature of the 'bug', so a B1 learner who knows both words will infer it is an insect with a wheel-like part or appearance. This compositional, descriptive pattern is common and non-idiomatic, so the basic meaning is directly derivable even if specific taxonomic details are not.

Etymology

Wheel bug gets its name from the spiny, wheel-shaped part on its back, so picture a tiny wheel sitting on a bug. That's why gardeners call it a useful 'predator' of harmful insects and why you should avoid touching it, because its bite can be painful.
