Mayflies go through a change called metamorphosis. Unlike butterflies that have four stages (egg, larva, pupa, adult), mayflies go through three stages. This is incomplete metamorphosis. Use the letters ENA to remember each step: Egg, nymph and adult.

What is the life cycle of a mayfly?
The life cycle of mayflies consists of four stages: egg, nymph, subimago, and imago. Eggs, which vary widely in size and surface detail, may be oblong, oval, or rounded. Depending on the species, a female may produce fewer than 50 or more than 10,000 eggs.
What insect orders have incomplete metamorphosis?
Insects that have an incomplete metamorphosis life cycle include true bugs, grasshoppers, cockroaches, termites, praying mantises, crickets, and lice.
How do mayflies grow?
The nymph emerges from the water as a dull-coloured sub-imago (or dun) that seeks shelter in bankside vegetation and trees. After a period of a couple of hours or more, the sub-imago once again sheds its skin to transform into the brightly coloured imago (or spinner).
Which stage of the mayfly lifecycle does the insect spend the most time in?
Surprisingly (to me at least when I first learned this) a mayfly spends most of its life living as a nymph under water. They will be a nymph for up to 2-3 years. Emerger – Once the nymph is ready to move on to the next stage in its life it needs to undergo a metamorphosis to a winged insect.
How long do mayflies live after they hatch?
Mayflies have an incredibly short lifespan.
After the larva stage, female mayflies usually live less than five minutes, while males can live a whopping two days.
What triggers mayfly hatch?
Most mayflies rise to the surface of the lakes at night when the water is usually calm. They float on the surface until their wings are dry and then fly away to complete their life cycle. . ... If the cold weather returns the mayfly hatches will be more drawn out and take longer to complete.
Does housefly undergo complete metamorphosis?
The house fly has a complete metamorphosis with distinct egg, larva or maggot, pupal and adult stages. The house fly over-winters in either the larval or pupal stage under manure piles or in other protected locations.
How do you know this insect is undergoing complete metamorphosis?
Insects that undergo complete metamorphosis typically appear quite different from the immature to adult stages. This life history typically has an egg, several larval instars, a pupa, and a final winged adult that is sexually mature.
What are mayflies eaten by?
Mayfly Predators and Threats
Caddisfly larvae and snails may eat the eggs of mayflies. Birds, dragonflies, fish, and water beetles eat mayflies that are in the early adult stage. When mayflies swarm, they tend to cause fish to swarm, which is helpful to fishermen looking for places to cast their lines.
Can mayflies bite?
Mayflies don't bite. They don't sting. They don't have mouths, so they don't even eat. They can live with that because they die in a day.
Where do mayflies go during the day?
Once the eggs hatch, these nymphs live near the bottom of the water, feeding on organic material. During this time as immature insects, fish and other insects will eat these nymphs. Once they mature, mayflies will leave the water, spending a day or two drying off and shedding their skin before flying away to mate.
What fly only lives for 24 hours?
Houseflies live for only 24 hours. A small house fly sits on the wet leaf of a plant on Nov. 14, 2012, in Bremerton, Washington's Blueberry Park. When it finally reaches its adult stage, the common housefly (or Musca domestica) tends to live for about two to three weeks, but can live up to a couple months.
Why are the mayflies so bad this year?
Unsurprisingly, reports are already showing a decline in birds that eat flying insects. Finally, declining mayfly populations are concerning, because mayflies are an indicator of water quality. Mayflies are highly sensitive to algal blooms, increased nutrient concentrations, and pesticides.
What insect has the longest lifespan?
The Longest-lived Insect: The queen of termites, known to live for 50 years. Some scientists believe that they live for 100 years. The Oldest Fossil Butterfly or Moth: A Lepidoptera fossil found in England is estimated to be 190 million years old.
