Morphology

true + bug

The phrase is a literal adjective+noun combination where 'true' qualifies 'bug' as a genuine/real insect, so a learner who knows both words will understand it denotes an actual insect. Although in biology it can refer specifically to Hemiptera (a narrower taxonomic sense), the basic composed meaning is transparent and immediately accessible to B1 learners.

Etymology

True bug is a name scientists used to mark the 'real' bugs, not every insect. They used true to mean the exact kind of bug: insects with a straw-like mouth that suck plant juices, so today true bug means that specific group of insects rather than any 'bug'.
