About Mayflies: the wider group

Order-level background for Ephemeroptera, the group containing Hexagenia bilineata. Species-specific details appear above.

Group overview

Ephemeroptera (mayflies) includes ~3,500 described species. Adult mayflies are famous for their extraordinarily short lifespans - some species live as adults for only 5 minutes to 24 hours, the shortest adult lifespan of any insect.

Ecological role of the group

Mayfly nymphs spend 1-2 years developing in freshwater before emerging as adults. They are key bioindicators - their presence indicates clean, well-oxygenated water. They are also a primary food source for freshwater fish.

Economic and practical significance of the group

Mayfly hatches are so massive they appear on weather radar - a 2014 Mississippi River hatch near La Crosse, Wisconsin was tracked by the National Weather Service. Mass emergences can cause slippery road conditions and traffic hazards.

Recorded sources for this group: National Weather Service, EPA bioassessment protocols. Imported estimates may describe particular regions or reporting periods.
