Root Explanation

Ephemerid is derived from the Greek word "ephemeros" (meaning lasting a day) and the suffix "-id" (meaning related to or belonging to). The term refers to insects that have a very short adult life span, typically lasting only a day.

Memory Tip

Think of the Greek word for 'lasting a day' — that's why ephemerid refers to insects that have such a brief adult life.
