    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.

    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.

    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.

    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.

    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.

    What a great resource!
    May I have permission to share your work with a couple of new fly fisher's?
    Thank you,

    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.

    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.
