This one pretty clearly keys to Kogotus, but it also looks fairly different from specimens I caught in the same creek about a month later in the year. With only one species of the genus known in Washington, I'm not sure about the answer to this ID.
Midges are the most important aquatic insects in some places, especially fertile spring creeks where they are extremely abundant and the current is so slow that it's efficient for trout to surface feed on very tiny insects.
Some midges are large, up to hook size 14, but the majority are size 22 or smaller. The number of genera and species is hopelessly huge for angler entomologists to ever learn, and the identifing characteristics often require slide-mounting tiny parts under high-powered microscopes. Even the most Latin-minded fisherman must slip back to the basics--size and color--to describe his local midge hatches.

Guys, what books besides Koch & Holbrook Midges books would you recommend for more on how and where midges live? I was reading an exerpt on midges from the book, Spring Creeks by Mike Lawson, and it seemed good. Koch & Holbrooks book is very good, but it seems to lack the how to fish pupa and when; where to find them, etc. I guess I'm looking for these kind of things plus habitat etc.

"Tying Small Flies", by Ed Engle is a good book but it is more of a "tying bench" book. It does offer some presentation advice, but it is geared more tword tying the patterns, as the name suggests. The reading I would suggest based upon your question would be the compainion book "Fishing Small Flies", by Ed Engle (Stockpole Books). Pages 136- 142 are specific to the "midge". I feel the whole book is a must read, along with "Tying Small Flies". Just because it is small does not automaticly make it a midge, remember "micro caddis" and mayflies. Another book worth a look is "A Fly Fisher's Guide to the South Platte River", by Pat Dorsey (Pruett Books). This book is specific to the South Platte drainage but I feel there are portions that would offer some valuble advice to you. Pages 118 - 122 are specific to midges, but through out there is good advice on technique. If nothing else it is a beautiful book and well worth the read. I could only imagagine that if I did not already live in Colorado and fish the South Platte 100 days a year it would make me want to.
I assume you posed this question because they will be the only major hatches here shortly, no matter where your home water is I am sure you will find value in the two I suggested and the suggestion made by "Softhackle". Remember to stay paitent this time of year, it will pay off.
