[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.

Ephemera danica can reach an imago size of 15–20 mm (0.6–0.8 in) in males, while females are larger, reaching 16–25 mm (0.6–1.0 in). This mayfly, with its characteristic markings and three tails (), is the most commonly seen of British Ephemeridae.
Ephemerids are generally quite large mayflies (up to 35 mm) with either two or three very long tails. Many species have distinctively patterned wings.
