Mayflies are mostly aquatic insects what are beneficial to ecosystem. Their infant or immature mayflies are referred to nymphs . They have an elongated or cylindrical flattened body that passes through stages and increasing in size as time passes by .
The thorax consists of three segments ; the mesothorax and metathorax, being fused together.whols the abdomen consists of ten segments, some of which may be obscured by a large pair of operculate gills, a thoracic shield or the developing wing pads.
In most classification up to seven pairs of gills arise from the top or sides of the abdomen, but in some species they are under the abdomen, and in a very few species the gills are instead located on the coxae of the legs, or the bases of the maxillae.

What Do Mayflies really Look Like?
Mayflies are thin and elongated insects with possession of two pairs of wings, six legs, and a set of antennae. Their styli are usually longer than their body. The size and color of a mayfly depend on the species. Some can be as small as 1-millimeter long while others can be up to 30-millimeters long.
Most have dark, dull-colored and yellow, gray, or even clear wings. They hold their wings together above their body when they’re at rest.
Mayfly naiads ( immature mayflies) may resemble the adults, but they don’t have wings. They have a characteristic appearance with a series of external gills attached either along their sides or on the top rear part of their abdomen. Their eyes are also smaller, and their heads are slightly flattened to allow them to hold on to rocks while they’re in the water.

Habitat
Mayflies are aquatic species, spending most of their lives developing in freshwater lakes, ponds, rivers, and streams. Though they’re no one’s favorite pest, their presence is a sign of a healthy water ecosystem, as they require clean water to survive.
In summary, Mayflies are aquatic insects and they live mostly in sea , lakes or ponds
Lifespan
The nymph stage of a mayfly can last between several months and two years. Adults are short-lived and typically last only a few days after emerging.
Most mayflies have one or 2 days of life span . The only mate and die .
Are they harmful to humans?
Mayflies are not harmful to humans and cannot bite. Mayflies are incredibly important within their ecosystems and help to maintain happy, healthy, natural environments.
Do mayflies bite or sting?
Adult mayflies cannot bite or sting because they literally lack the mouthparts to do so. Their digestive systems are filled with air they can’t eat, drink, or do anything other than mate and die.
Mayflies have vestigial mouth parts that cannot bite. Adults have long tails that may appear menacing, but are harmless. Mayflies do not have stingers.
What insects consume mayflies as diet in the wild ?
Mayflies play a critical role in the aquatic food chain. Snails and caddisfly larvae consume mayfly eggs. Fish, frogs, birds, flies, and water beetles may consume the nymphs. Fish, birds, dragonflies, water beetles, and other predatory insects consume subimagos.
Mayflies at their subimago stage are a favorite diet of many fish, and many fishing flies are designed to look like them. Mayflies as adults are an essential food source for trout, bass, catfish, frogs, newts, and birds.
The level of predation on mayflies varies depending on the season, the size of the nymphs, and the behavioral patterns at the time. Mayfly nymph p
