Interesting about the mayfly

  • Mayflies or Ephemeroptera are flying insects that live only a few minutes, hours or days after the larval stage, depending on the species.
  • Within the mayflies will differ between three thousand species. Of these, about three hundred are native to Europe.
  • Mayflies occur on all continents with the exception of the polar caps and dry deserts, although they are much more abundant in temperate climates and mountainous regions than in the tropics and subtropics.
  • Depending on the species, the adult insects are between three millimeters and almost four centimeters long.
  • All mayflies are the eye-catching compound eyes, the large, veined and often patterned wings and the slender and elongated abdomen common.
  • The adult mayflies have a dysfunctional digestive system and stunted mouthparts because they do not eat during their short life as an imago.
  • In the warm summer months, especially in the evening, mayflies occur in such large swarms that they are perceived as a real plague in many places. Since many species appear in May, the mayfly in English is called Mayfly.
  • Before the mayflies die, they mate. On summer evenings, the mating flights can be observed above the water surface of lakes, rivers, streams or ponds.
  • The females then give their eggs to the water before they die of exhaustion.
  • Striking in the female and male mayflies are the externally arranged on the abdomen sex organs.
  • The larvae, which can be of elongated, round or flattened body shape depending on the type, live in the water for up to three years after hatching and feed on rotten plant material.
  • Depending on their way of life, a distinction is made between burrowing, floating, crawling and stone-clipping larvae.
  • Adult mayflies are an important food source for fish, beetles and their larvae as well as other flying insects.
  • Many species of mayflies have already been eradicated, as they lay their eggs in contaminated waters that inhibit the development of larvae due to their toxic nature.
