Mayflies of North America Poster Series

This new poster series is being offered by Scott and Nix, who also sell numerous other fish and bird related art and publications.

Using original art loaned from the Schwiebert estate, each of the 12 ×
18 inch posters features 30 illustrations of natural mayflies in
perfect pose, just as Schwiebert illustrated them. From tiny Blue
Winged-Olive “Psuedos” to massive Yellow Drakes and Coffin Flies, here
are all the mayfly species that are important to anglers across the
continent.
