Morphology

oil + beetle

The noun–noun compound is compositionally transparent: 'oil' modifies 'beetle,' so the phrase denotes a beetle associated with oil (i.e., one that produces or is covered with an oily substance). This follows a common, cross-linguistic compounding pattern, so a B1 learner who knows both constituent words can reasonably infer the intended meaning.

Etymology

The compound name oil beetle comes from a simple image: this small beetle gives off an oily drop from its legs when it feels threatened. That's why people named it for the oil, because the liquid helps the insect 'defend itself'.
