Mayfly larvae do not survive in polluted aquatic habitats and, thus, have been chosen as bioindicators, markers of water quality in ecological assessments. [ 100 ] In marketing, Nike produced a line of running shoes in 2003 titled "Mayfly".
Adults appear in summer and are found near still and slow-moving water. The nymphs are found burrowing in the mud and silt in shallow lakes and slow-moving streams and rivers. This mayfly is generally more abundant than the closely related Hexagenia limbata, but that species becomes more plentiful from Keokuk, Iowa northwards.
If threatened by a predator, the larva will raise its three tails in a "scorpion posture" to appear larger. It will then project its tails in front and poke the enemy. Most species are sensitive to disturbance. In the UK, the most commonly recorded species is Seratella ignita. The nymph of this animal is often distinguished from other Mayflies ...

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.
Ephemerids are generally quite large mayflies (up to 35 mm) with either two or three very long tails. Many species have distinctively patterned wings. [2] They breed in a wide range of waters, usually requiring a layer of silt as the nymphs have strong legs which are adapted for burrowing (the group is sometimes known as burrowing mayflies).
Dolania is a monotypic genus of mayfly in the family Behningiidae containing the single species Dolania americana, also known as the American sand-burrowing mayfly. [2] It is found in the southeastern United States, as far south as Florida, and is generally uncommon. [ 3 ]
Its abundance is unknown. The Tomah mayfly is the only species within the monotypic genus Siphlonisca. [2] The Tomah mayfly is a habitat specialist and an indicator species. [3] Adults only live for a few days as they deposit eggs into rivers and streams. [4] Nymphs hatch from eggs and migrate to the floodplains during springtime and following ...
