Morphology

June + beetle

The meaning — a beetle associated with the month of June/late spring — is directly and transparently derivable from combining 'June' (the month) with 'beetle' (an insect). This simple noun+noun composition is predictable and cross-linguistically common, so a B1 learner who knows both words will readily infer the MWE's basic meaning.

Etymology

The name June beetle comes from the simple image of a big, brown beetle that appears in June, often clumsy around porch lights. Because these insects are most common in late spring and their larvae eat grass roots, the name came to mean 'a large beetle people see in early summer'.
