They are even found on the shores of lakes and beaches where there is wave action present.

If threatened by a predator, the larva will raise its three tails in a "scorpion posture" to appear larger.

The nymph of this animal is often distinguished from other Mayflies by the darker bands prominent on the legs and tails.

Although another rare species Ephemerella notata lacks these prominent bands and so is more difficult to identify.

They have reduced mouthparts because the adults just emerge to mate and then die shortly after.

Their wings are membranous and heavily veined to add strength since the adults must find one another through flight.

Their lightly sclerotized abdomen contains many segments for ease of mating positioning.

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.

Additionally, mayflies- along with Trichoptera and Plecoptera- are frequently used as biological indicators.
