'adephaga' originates from Greek, specifically the word 'adephagos,' where 'a-' meant 'not' and 'dephagos' meant 'gluttonous.'

'adephagos' transformed into the scientific Latin term 'adephaga,' and eventually became the modern English term 'adephaga.'

Initially, it meant 'not gluttonous,' but over time it evolved into its current meaning of a suborder of beetles.
