In the north of England and most of Scotland the term mayfly is generally used for all species in the order Ephemeroptera. ... The common name comes from the habit of one species, Ephemera danica, which emerge as adults when the Mayflower or Hawthorn is in bloom. Mayflies are an ancient group of winged (pterygote) insects. ... The name Ephemeroptera is from the Greek ἐφήμερος, ephemeros "short-lived" (literally "lasting a day", cf. English "ephemeral"), and πτερόν, pteron, "wing", referring to the brief lifespan of adults. What are mayflies good for? Mayflies not only move nutrients within aquatic ecosystems, but they also move nutrients between them. This may be important for maintaining a variety of aquatic communities, especially if various climate forecasts hold true. Why do dragonflies dance? “The movements we observed are so fine-tuned that they keep the image of the prey fixed in the crosshairs of the dragonfly's eyes – their area of greatest acuity – during the duration of the chase. That allows the dragonfly to receive two channels of information about its prey,” Dr Leonardo said. What do Dragonflies symbolize? A dragonfly is a symbol of change, transformation and self-realization. It teaches us to love life, to rejoice and have faith even amidst difficulties. Is a dragonfly a good omen? Dragonflies can also be omens. If a dragonfly lands on you, it is seen to be good luck. Seeing a dragonfly in dreams or if one suddenly appears in your life, it is a sign of caution.
