Acentrella nadineae
small minnow mayfly
Acentrella nadineae is a small minnow mayfly in the family Baetidae. The species was described in 2009 and remained known only from nymphs until successful rearing produced the first documented adults. It inhabits cool, clean, swift rocky streams across parts of the eastern and midwestern United States. Near final instar nymphs exhibit unusual madicolous behavior, living in thin water films on rock surfaces.
