Origin

Mid 17th century (denoting a disembodied spirit or ghost): from Latin, literally 'ghost, mask'.

‘A disembodied spirit or ghost’ was the first use of this Latin word which means literally ‘ghost, mask’. The common modern use as a term for the active immature form of an insect is due to the Swedish botanist Linnaeus (1707–78).
