'agrilus' originates from Greek, specifically the word 'agrilos,' where 'agri-' meant 'field' and '-los' was a diminutive suffix.

'agrilos' transformed into the Latin word 'agrilus,' and eventually became the modern English word 'agrilus' through scientific classification.

Initially, it referred to a small field beetle, but over time it evolved into its current meaning of a genus of metallic wood-boring beetles.
