Description: Ephemerids are burrowing mayflies (along with larvae of Polymitarcyidae). As indicated under Polymitarcyidae, Ephemeridae have tusks turned up and without spines; whereas Polymitarcyidae larvae have tusks turned down and with spines. The photo specimen of Hexagenia limbata is about 25 mm in length. Hexagenia larvae are found mainly in large streams and lakes, where they burrow into fine sediment. Probably most populations of Hexagenia limbata have one-year life cycles. Hexagenia is the main culprit in the large mayfly emergences that take place in the upper Mississippi River drainage.
