The nymphs are highly susceptible to pollution and can be useful in the biomonitoring of water bodies. [4] Once they have emerged, large numbers are preyed on by birds, bats and by other insects, such as Rhamphomyia longicauda. [5] Mayfly nymphs may serve as hosts for parasites such as nematodes and trematodes. Some of these affect the nymphs ...
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.

They eat small particles of organic matter, such as algae, plant residues or decaying plants. Nymphs show an elongated and round shaped body, reaching a length of about 10–12 mm (0.39–0.47 in).
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. They have created a large market for fly fishing and have had a positive impact on the economy by selling the materials to make flies as well as the ...

The nymphs of E. vulgata burrow into the sediment at the bottom of ponds. Most burrowing mayfly nymphs use the gills on their abdomens to create a current of water through their burrows, thereby ensuring sufficient oxygen is available to absorb through the tracheae in their skin.
Hexagenia bilineata is a species of mayfly in the family Ephemeridae. It is native to North America where it is found in the Upper Mississippi Valley.
