MAJOR RIVER HATCH CHARTS

---

If you scroll down the page, you will see a more generalized hatching chart that has the scientific or latin name for some of these insects. Some of these currently have links to them. When you click on a link it will take you to a photo and description of the fly you're looking at. I will be updated this chart on a somewhat daily basis (as time permits).

LAST UPDATED: JUNE 13, 2005

Some of the species below have been underlined for your convenience. Clicking on some of the underlined names will bring

you to an actual photo of the species and possibly a photo of the imitation that matches the species.

Please Note, depending on the area you are fishing, hatches may vary by a week or two.
