Morphology

May + bug

The meaning is directly compositional: 'May' (the month) + 'bug' (an insect) signals an insect associated with May. This month+animal naming pattern is cross-linguistically common, so a B1 learner who knows both words will readily infer it refers to an insect that appears in May (even if they may not know the exact species or biological details).

Etymology

May bug gets its name because the large beetle is often seen in May and the word bug simply means an insect. It flies at night in late spring and its young live in the soil and eat plant roots, so the name reminds us this large spring insect can harm plants.
