Morphology

ephemerid = ephemeral (semi-transparent) = ephemer + id

The connection to 'ephemeral' (short-lived) is clear, but the suffix '-id' functions as a taxonomic/member marker and the specific identification as a mayfly is specialized vocabulary not predictable for most learners.

Etymology

Ephemerid comes from the same root as ephemeral, which means 'lasting a short time'. The root comes from hemera meaning 'day', so an ephemerid is an insect that often lives only one day.
