[18] Many species breed in moving water, where there is a tendency for the eggs and nymphs to get washed downstream.

[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.
