Description: 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.
