Mayfly Species Paraleptophlebia helena (Mahogany Dun)

This large species of Paraleptophlebia is one of the tusked group. Records indicate it is endemic to California where it fills the niche taken by Paraleptophlebia bicornuta in neighboring states. It usually hatches with the more common and very similar looking duns of Paraleptophlebia debilis.
