caption_attribution_description: Deutsch: Eine weibliche Subimago (ein geflügeltes Vorimaginalstadium) der Märzbräune (Rhithrogena germanica) aus der Familie Heptageniidae. Die Subimagines besitzen eine behaarte Haut (Subimaginalhaut), die auch die Flügel überzieht. Diese sind deshalb bei den Subimagines stets etwas trüb und haben häufig, wie auch bei R. germanica, eine bestimmte Musterung. Imaginalflügel sind hingegen in aller Regel hyalin und klar durchscheinend. 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 aus der Klasse der Schachtelhalme (Equisetopsida). English: A female subimago of March Brown (Rhithrogena germanica) mayfly in the family Heptageniidae. Mayflies are insects which belong to the Order Ephemeroptera (from the Greek ephemeros, short-lived and 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. It is resting on a Rough Horsetail Equisetum hyemale stem. Français&#160;: Un subimago femelle de (Rhithrogena germanica) sur une fructification de Prêle. Rhithrogena germanica est une mouche de mai ou éphémère de la famille des Heptageniidés. Rhithrogena germanica est une espèce répandue en Europe, sur toutes les rivières, mais avec une prédilection pour les eaux froides et oxygénées de moyenne montagne.
