Blue-winged Olives

Tiny Baetis mayflies are perhaps the most commonly encountered and imitated by anglers on all American trout streams due to their great abundance, widespread distribution, and trout-friendly emergence habits.

27" brown trout, my largest ever. It was the sub-dominant fish in its pool. After this, I hooked the bigger one, but I couldn't land it.

Troutnut is a project started in 2003 by salmonid ecologist Jason "Troutnut" Neuswanger to help anglers and fly tyers unabashedly embrace the entomological side of the sport. Learn more about Troutnut or support the project for an enhanced experience here.

I found this helpful web site by accident this afternoon while researching the body color of the Grannom found on the Little Juniata. The site lists the Latin name and I think the colloquial name. Then it goes on to provide the body and wing colors and the names of common fly patterns that represent that insect and it even provides data on how to fish the fly.

Then if you scroll down you can select another insect to find data on it.

Wbranch,

Westfly, along with this site, has been one of my go-to resources for bugs and patterns to match them with, for a very long time.It is the most comprehensive site for for Western Fly Fishing that I have found. Another site I frequent is Steve Schalla's "Fly Fishing The Sierra", which has just about everything one would want to know about visiting and fishing that part of CA:
