American Blue Duns
Like most common names, "American Blue Dun" can refer to more than one taxon. They're previewed below, along with 1 specimen. For more detail click through to the scientific names.
Mayfly Species Paraleptophlebia praepedita
These are sometimes called American Blue Duns.
This species may reinforce hatches of Paraleptophlebia debilis.
Mayfly Species Paraleptophlebia adoptiva
These are very rarely called American Blue Duns.
This is the best Spring hatch after the Quill Gordons (Epeorus pleuralis) but before the Hendricksons (Ephemerella subvaria) in most parts of the East, although it can overlap with both. The Blue Quills are small mayflies (hook size 16-20) but they can hatch in incredible numbers at a time when eager trout are just beginning to look to the surface after a hungry winter.
