What is a mayfly?

what is mayflyMayflies are small flies with long curved bodies and wing-set. They look very much the same as larger versions of dragonflies or damselflies. They are also called shad flies or lake flies.

Mayflies also have a double ‘tail’ extending from their body and also aquatic insects.

They are about 5'2 inches long with two antennae indicating that they're neither mosquitoes nor snakes.

There are thousands of species of mayflies worldwide and there are currently more than 400 genera in 42 families. The body is typically black, yellow, or other shades of dull colors.

Wings are always transparent, although they may have darker layers. Generally, this is a member class of The Ephemeroptera order.

What does a mayfly look like?

Mayflies become another aquatic species that float quickly when they are swimming. Its length is about 1" and its wings are large.

They can have two or three tails in place of their body when traveling. Mayflies often find Mayflies in black or stripes.

They have large wings and 6 legs and dark colors with tiny antennas.

The anatomy of the mayflies for birds is fairly standardized. They are between 1' and 1" long.

They were seen with dark colorations with small antennal holes and black with stripes along with their wings.

The life cycle of a mayfly?

Mayfly passes four phases. They are laid and begin at the egg stage. Egg colors and sizes will vary depending on the species. Between 80,000 and 100 million eggs are produced.

Mayflies are seen from the same animal in the same color or in different breeds.


Adult female mayflies lay eggs in the ground and then sink into the mud to settle onto the bottom soil.

Immature insects (also known as nymphs) hatch from eggshells and settle at the bottom of the pond.

They are highly sticky and range from the circle, round to sphere. After egg production, the eggs are laid within 24 hours.

This depends on the climate temperature the time the egg stays incubated or on other factors.

There will also be periods during which eggs would stop growing fully known as diapause.

This prevents hostile conditions for immature mayflies (nymphs) from developing in each egg. It gives mayflies an opportunity to populate and grow rapidly.

Aquatic mayfly nymph (unwinged)

After their birth, the nymphs continue their evolution for at least 24 months. The Molt phase can have many molts during this phase.

Mayflies begin their life cycle as aquatic insects and only fly when they reach adulthood.

A nymph molts 50 times and at this stage, the skin is split. Here is the Subimago version (also known as the dun) and finally the wings emerge.

In addition, they will continue their limbs and tails and grow shorter during a certain phase in their cycle. Mayflies have come second to last.

Adult mayflies (winged)

A female adult mayfly only has wings for a very short duration. Then the molting can take part after the mature adult mayfly has successfully mastered.

During the mating period, Male and female mayflies will mature and the female egg will be deposited, also known as the oviposition.

This period lasts only for several hours and the person can quickly die after the age of ten. When in rest, these aquatic insects hold their wings together in front of them.

In a sperm pool, the female sex must remain firmly anchored until they mutilated. They are the only species known to molt after wings have deviated.

Egg deposit

She flies and mayflies deposit a number of eggs in water channels. Some will fly near the water's surface dragging her abdomen into the water.

They can also put up objects from the water or even deposit them on the underside to help with water movement.

After egg collection, the female will die shortly. Mayflies only stay for just a few days in adulthood.

Mayflies Lifespan

Mayflies can live for a few hours, while some may stay up to one day after adulthood.

What do mayflies eat?

These aquatic species can scavenge tiny plants or algae sifted onto pieces of stones or wood that would be discarded with water.

Adult mayflies will also feed on various vegetables and continue to take algae diets above water.

But despite their vestigial mouths, it is unlikely that they will eat. They can dig to the bottom of the ocean and search out the algae found in other layers.

Even as adults they may be found with a pair of wings. Mayflies also consume different types of algae in the water in the wild and they eat floating algae in water in the middle of the water.

Note mayflies will go underwater even if they are wings.

How long do mayflies live?

During their aquatic life as a nymph, they have vestigial mouthpieces, which does not actually have a full mouth.
