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.

Nymphs of this species were fairly common in late-winter kick net samples from the upper Yakima River. Although I could not find a key to species of Zapada nymphs, a revision of the Nemouridae family by Baumann (1975) includes the following helpful sentence: "2 cervical gills on each side of midline, 1 arising inside and 1 outside of lateral cervical sclerites, usually single and elongate, sometimes constricted but with 3 or 4 branches arising beyond gill base in Zapada cinctipes." This specimen clearly has the branches and is within the range of that species.
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.

I've been thinking about increasing my fly tying materials, I'm going to buy some shuck material but I don't want to buy every color under the sun, so here's my question what are the most popular colors for fishing eastern Pennsylvania ?

dark brown, brown, olive, amber, clear or white. That will cover pretty much all the mayflies and caddis. Most of the ephemerellids, (Sulphurs, hendricksons, drunellas) all have dark shucks, Baetids are variable from brown, olive to amber. Brown will cover most other mayflies. Caddis pupal shucks are clear. Some common ones have a tannish/amber tint. That material will take a permanet marker too so you can use a sharpie or pantone to make it any color you want.
