Blue-winged Olives
Baetis

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.

Dorsal view of a Limnephilidae (Giant Sedges) Caddisfly Larva from the Yakima River in Washington

This specimen resembled several others of around the same size and perhaps the same species, which were pretty common in my February sample from the upper Yakima. Unfortunately, I misplaced the specimen before I could get it under a microscope for a definitive ID.

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.

Here are a few simple flies you might try--

For active (skittering) adults: Try a white Elk-Hair Caddis, (+/-) #14. If you are tying your own, you might want to add a very pale green body and a light ginger or cream hackle under the light elk- or deer-hair wing.

For spent (flush in the film) adults: Use the same pattern minus the palmered hackle (or just fish the above fly untreated and soggy).

For submerged (drowned or diving) adults: The classic White Miller wet fly works (but add a pale green body if tying your own).

For emerging pupa: You probably won't find a commercial pattern to match the pupa; so tie a soft-hackle style with a pale green (or cream) body ribbed with pearl Krystal Flash, a tan shoulder (thorax) and a collar of the palest partridge you can find.

Good Luck!
