WA Hatch Chart Upgrade

Discussion in 'Fly Fishing Entomology' started by Taxon, Aug 16, 2013.

  1. My WA Aquatic Insect Emergence Chart has now been upgraded to link to representative larval and adult photos of most genera featured in the chart. If you have feedback, please share.

  2. That has to be one of the best hatch charts I've ever seen, and I live in California! I have a question for you also. This spring in May, I was on the lower Sacramento River and I found a dozen Claassenia sabulosa's under some rocks in a very shallow rifle. They were fully mature, and I hatched them out of my aquarium in one week. Why did they hatch May and not in the fall? And also a guy I know found the giant female and short winged male nymphs under rocks by the shore, not hatching, because it was the middle of the day, but almost as if they were feeding on something.Explain that.
  3. Excellent Roger, thank you!
  4. Hi TE-
    Thank you.
    Claassenia sabulosa have an extended emergence period, which runs from early-Jun to mid-Nov, depending on where they are. If the water in your aquarium was warmer than the water from which you collected them, their emergence would be accelerated.
    The males hide under rocks, etc. by day, and venture out on search of females after dark.
  5. Taxon, you are a genius. I just want to tell you that I'm only 14. Thanks again.[​IMG] My favorite insect, zee pteronarcys californica.

  6. Hi TE-

    Ha, don't I wish. ;) Age apart, you obviously share my enthusiasm for aquatic insects.
    Yes, as the largest stonefly, they are a favorite of trout as well.
  7. Wow! Now there's an extremely useful reference. Thank you!
  8. Recently, I was looking at the previous hatch chart and was thinking how great it was to have that resource available. :)
    Thanks for the upgrade.
  9. Richard Torres, Jim Fricklin, and astrofisher-

    Thanks for the kind words.
  10. Roger,
    What a great resource!
    May I have permission to share your work with a couple of new fly fisher's?
    Thank you,
  11. Hi Chris-
    Thanks. Please PM me with your full name, email address, and the specifics of what you propose doing with my work. I will respond via email to your request.

    I just noticed the hook sizes to the right.
    what a good idea and a great chart
  13. Thanks, Jay-

    Including hook sizes on a hatch chart was certainly not my idea. The first time I recall seeing it was on a hatch chart developed by Larry Graham for the Yakima River. Larry was a Yakima River fly fishing guide, who was also widely recognized for his expertise in aquatic entomology, and developed the highly effective "Lightning Bug" fly pattern. In any event, I have simply attempted to incorporate the good ideas of many others into a single hatch chart for WA.
  14. Thanks for all your hard work that's awesome
  15. Fantastic stuff. Thanks!
  16. This is fantastic!

    Thanks for providing such a great service to your fellow fly fishermen. There is a huge amount of information here.
  17. Joe, tkww, and Steve,

    Thanks for your kind words.
  18. That is a solid upgrade! Thanks for maintaining the site!
  19. Thanks, Matt. It's something I have intended to do for several years, but never seemed to get around to, as it took quite a bit of work to accomplish.
  20. You really need to create an android app.
