What Are Mayflies?

Mayflies are commonly known as fishflies and shadflies in Midwestern America and Cana. Some people also call them winged flies in the UK. Mayflies are aquatic insects that belong to the Ephemeroptera family, which is an ancient insect group. This group also includes damselflies and dragonflies. On top of everything, do you know that mayfly has over three thousand species, categorized into 42 families and more than 400 genera?

Mayflies tend to show off the ancestral trails – the ones that come from the first flying insects, including wings and long tails that don’t fold over the abdomen, not flatly at least. They lay eggs in the fresh water and are known as nymphs. If a freshwater body has these mayfly nymphs, it means that the aquatic environment is oxygenated, unpolluted, and clean. Mayflies are different from other insects by having winged stages and subimago which then grow into mature adults, known as imago.

Mayflies are known to hatch during the autumn season, but their growth starts in the spring season. Generally, this phase starts in May, but it can fluctuate as well. On top of everything, the mayflies are used by fly fishermen as bait. The mayflies tend to be active during the warm seasons as well.

These insects are found around the world, but they are most common in North America. Also, they choose clean rivers and streams to hatch and grow. As for nurturing and growth, the larvae are likely to feed on detritus as well as other plant materials, but some of them consume smaller insects as well. On the other hand, adult and mature mayflies don’t eat.

The female mayflies lay eggs in water and spend most of their life in water, and within a short period, they transform into adults. Surprisingly, the adults only live for a day or two, but the larvae can survive for up to one year. The mature mayflies have two pairs of wings with a pale color and a slender body.
