Out of all the mayfly species in the family Ephemeridae, they are the most common in North America. [3] The nymphs of the species burrow and can be found the same time as the Green Drake (Ephemera guttulata) mayflies, which the species acts similar to; if one trout stream has a hatch of E. simulans , there might also be a hatch of E. guttulata ...

Hexagenia limbata, the giant mayfly, is a species of mayfly in the family Ephemeridae. It is native to North America where it is distributed widely near lakes and slow-moving rivers. [ 2 ] The larvae, known as nymphs, are aquatic and burrow in mud and the adult insects have brief lives.
Mayflies are commonly used as models for fly fishing lures. Both the nymphs and the adults are common food among the aquatic stream world. With their long tails, they are very attractive bait for many species of trout, and in some cases small mouth bass.
Ephemera vulgata can be told in both adult and subimago stages from the rather similar green drake (Ephemera danica) by its duller colour and slightly smaller size.The wings are more heavily veined and the upper side of the abdomen has pairs of dark lateral markings on each segment.
