Fly Charts

Welcome to our Fly Charts Page.  We hope you’ll find our Mayfly and Caddis ID & Hatch Matching charts useful.  All charts are waterproof and sized to fit in the same fly fishing vest pocket as a large fly box (4.5" x 8.5").  They provide the angler with all the information needed to determine species and appropriate fly selection for the 25 most common hatches, as well as detailed information on fly behavior to aid in on-the-stream presentation.  Single charts (2 sided) are available for $4.95 each.  If you purchase a Mayfly and a Caddis Chart together the cost is $8.95 for both.  We also have a free instruction sheet available as a pdf download.  And the best part?...all net proceeds go to trout habitat improvement projects!

We strongly believe you’ll find our ID and Hatch Matching Charts to be the best you can find anywhere, at any price. Why?  Just look at what you’ll get:

  • Waterproof---you can take them down to the river,
  • Convenient---you can keep these 4.5” x 8.5” cards in a vest or pack,
  • Coverage---our charts cover all the common patterns: nymphs, emergers, adults and ovipositors,
  • Genus/Species ID---a complete ID description of each genus/species covered,
  • Drawings---to assist in your ID,
  • Hatch Matching---all you need to know to match species for the 25 most common fly patterns,
  • Action---behavior patterns for nymphs, emergers & ovipositors, to assist in your fly's presentation,
  • Habitat---areas the nymphs and larva prefer, so you’ll know what section of water is most productive,
  • Up To Date---we keep current with the ever changing scientific nomenclature,
  • Completeness---not equaled in any one book.  We've combined the results of over dozens of books, hundreds of photos, scholarly journals and personal observations.

And that's right, 100% of the net proceeds from the sale of each chart this year, 2013, are being donated to WTF's Wild Trout Fund---for Wild Trout habitat improvement projects to help insure future generations continue to enjoy our great sport of fly fishing.

We've provided a reduced sized example of both sides of the Caddis Card below.  The Eastern Mayfly Card is similar, though of course tailored to the unique qualities of Mayflies.  We hope to come out with a Western Mayfly Card soon, as well as an expanded size cards with larger type, and to offer all these cards through area fly shops later this year.  Glenn Erikson, PhD researched, put together and copyrighted the information on the fly charts, with the design assistance of master printer Rich Machin, of RFM Design.
