What is the larvae of a mayfly?

Mayfly larvae (also called naiads or nymphs) are slender and soft-bodied, like adults, though they lack wings, have a series of leaflike or feathery external gills attached along the sides or on the top rear portion of the abdomen, have smaller eyes than adults, and often have a flattened head that helps them to adhere …

How do you detect Ephemeroptera?

Ephemeroptera are aquatic insects that often go through many nymph stages (living in water) and two flying stages (the subimago and the imago). They are the only insects to have two flying stages, and can be recognized by their three caudal filaments (tails) at the tip of the abdomen, and a single claw on each leg.

How do Ephemeroptera reproduce?

The male grabs a passing female with its elongated front legs and the pair mate in flight. After copulation, the male releases the female, which then descends to the surface of the water where she lays her eggs.

How long do mayfly larvae live?

Mayflies spend most of their lives in the water as nymphs and then emerge as adults for only a short while. Adults will live only a day or so, but the aquatic larvae lives for about a year. Their status is unknown. There are more than 600 species of mayfly in the United States and 3,000 worldwide.

What are mayflies good for?

What triggers a mayfly hatch?

Water temperature is the most important factor in determining when hatches will occur. And though a specific hatch date may deviate as much as a month from one year to the next, the order in which the various mayfly species emerge always remains the same.

What do Ephemeroptera larvae eat?

The chironomid larvae attach to the cuticle of the mayfly and eat the unicellular organisms that live there. More harmful to mayflies are nematode parasites, who use nymphs as their hosts by eating their muscles from the inside. Ephemeroptera nymphs are usually microhabitat specialists.
