Insects introduction- mayflies

Mayflies
Mayflies are insects which belong to the Order Ephemeroptera (from the Greek ephemeros = "short-lived", pteron = "wing", referring to the short life span of adults). They are aquatic insects whose lasts one year in freshwater. The adults are short-lived, from a few minutes to a few days depending on the species. Common names for mayflies include "Canadian Soldiers", "dayfly", "shadfly", "Green Bay flies", "june bugs", "lake fly", "fishfly","midgee", and "jinx fly".
It often happens that all the mayflies in a population mature at once (the hatch), and for a day or two in the spring or fall, mayflies will be everywhere, dancing around each other in large groups, or resting on every available surface. In certain regions of New Guinea and Africa, mayflies are eaten when they emerge en masse on a certain day.
Because of its short lifespan, the mayfly is also called one–day fly in some languages — French éphémère, German Eintagsfliege, Dutch eendagsvlieg, Slovenian enodnevnica, Swedish dagslända, Danish and Norwegian døgnflue, Polish jętka jednodniówka, Finnish päivänkorento,Turkish birgün sineği Spanish efímera, Romanian efemeride, Russian поденка, Bulgarian еднодневка, and Greek εφήμερος.
