Neoleptophlebia memorialis Mayfly NymphNeoleptophlebia memorialis Mayfly Nymph View 8 PicturesThis specimen keys to the Neoleptophlebia memorialis group, which means it could be Neoleptophlebia memorialis or Neoleptophlebia temporalis. In the absence of a clear species key, I'm just guessing memorialis for now.
