Great Red Quills
This common name refers to only one species.
Mayfly Species Timpanoga hecuba
These are often called Great Red Quills.
Timpanoga hecuba is not abundant enough, and its emergence not concentrated enough, to provide great hatches, but where it is locally abundant it creates fishable action because of its large size. It is one of the largest species in the Ephemerellidae family, being almost the size of Drunella grandis, the Western Green Drake.
