Mayfly Species Epeorus vitreus

These are sometimes called Gray-Winged Yellow Quills.
This is the second most common Epeorus species in the East and Midwest. Most anglers will encounter sporadic hatches of Epeorus vitreus once in a while, and sometimes a more concentrated emergence causes a good rise of fish.

Mayfly Species Leucrocuta hebe

These are very rarely called Gray-Winged Yellow Quills.
This widespread species produces more fishable hatches in the East and Midwest than any other species in the Heptagenia genus complex.

Each of these stages is known as an instar. Hard-bodied nymphs typically molt through more instars than soft-bodied larvae.).
