Description Deutsch: Eine weibliche Subimago (ein geflügeltes Vorimaginalstadium) der Märzbräune (Rhithrogena germanica) aus der Familie Heptageniidae. Die Eintagsfliegen (Ephemeroptera, auch Ephemoptera; von gr. ephemeros - eintägig, pteron - Flügel) sind die ursprünglichsten unter den Fluginsekten (Pterygota). Es gibt sie schon seit 200 Millionen Jahren. Die Eintagsfliegen bilden eine Ordnung innerhalb der Klasse der Insekten (Insecta). Von den bekannten 2.800 Arten leben in Mitteleuropa mehr als 100. Die Eintagsfliege im Bild ruht auf einem Winter-Schachtelhalm (Equisetum hyemale), auch Zinnkraut, Acker-Zinnkraut, Katzenwedel, Schaftheu, Pfannebutzer oder Scheuerkraut genannt, und ist eine Pflanzenart aus der Klasse der Schachtelhalme (Equisetopsida).

English: A female subimago of March Brown (Rhithrogena germanica) of family Heptageniidae. 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 have been placed into an ancient group of insects termed the Paleoptera, which also contains the dragonflies and damselflies. They are aquatic insects whose immature stage (called naiad or, colloquially, nymph) usually lasts one year in fresh water. As shown a Mayfly on a Rough Horsetail (Equisetum hyemale) which is a rather bushy perennial with a rhizomatous stem formation native to the northern hemisphere.
