The term “dayfly” refers to a type of insect belonging to the order Ephemeroptera, commonly known as mayflies. Dayflies are characterized by their short adult lifespan, often lasting only a few hours to a couple of days. They are known for their delicate, translucent wings and their habit of emerging in large swarms, particularly during warm months. The name “dayfly” highlights their brief adult life stage, which contrasts with their longer nymph phase spent underwater.
