Like most common names,"Early Black Quill" can refer to more than one taxon. They're previewed below, along with 3 specimens. For more detail click through to the scientific names.
Mayfly Genus Leptophlebia
These are sometimes called Early Black Quills.
Leptophlebia mayflies do not generate superhatches, but their medium-large size and other properties make them a relevant part of the early season.
