'insectological' originates from the Greek word 'insectum,' meaning 'cut into,' and the suffix '-logical,' which pertains to the study or science of a subject.

'insectum' transformed into the Latin word 'insectum,' and eventually became the modern English word 'insectology' through Middle English.

Initially, it meant 'the study of insects,' and this meaning has largely remained the same in modern usage.
