    Roger, I have a question. I think I see the answer, but I want to double-check: The different genera are listed in order of emergence date?

    One area I've been keeping an eye on in my own knowledge base is caddisflies. Granted, my perspective is heavily focused on be-prepared-to-fish-the-bug/hatch. So prevalence or likelihood of encountering is also at the forefront of my thinking. And timing/emergence is certainly a part of that(!!), as is the time of day--thanks for including that information on the mayflies and caddisflies!

    But I'm also wondering if there is any other indicators for how common a particular genus is. Obviously this could vary greatly from one body of water to another for any number of reasons, but in the overall scheme of things... Is it fairly safe to assume that the longer the hatch period, the greater the density or more likelihood of encountering through sheer numbers?

    Nice chart Roger. I printed it off so I can hang it on a tying room wall.

    Hi tdww-

    Yes, start of emergence within order.

    No, not really, as some intense emergences are quite short in duration. There is no good substitute for genera-level knowledge of emergence behavior, and for western mayflies, the best source for that knowledge is Western Mayfly Hatches by Rick Hafele & Dave Hughes.

    There are a few semi-local rivers/streams where your hatch chart gives tips on what to put in the fly box.

    Hi Bill,

    Not sure what you are saying; perhaps you could provide an example?

    We've got some semi-local spring creeks and also two freestone rivers.... the Yakima and Kettle where this chart should give tips on what to have in the fly box.

    Bill,

    It's a generalized emergence chart for all the streams and lakes in the State of Washington. However, it does have links to photos of the insects you should have imitations for in your fly box.
