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.
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.
Palingenia longicauda is an aquatic insect in the order Ephemeroptera.It is known as the Tisa or Tisza mayfly after the European Tisza river where it is found and also as the long-tailed mayfly and giant mayfly since it is the largest mayfly species in Europe, measuring 12 cm (4.7 in) from head to tail.

Eulimella torquata was first described in 2011, and has no common name.
