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.

This one seems to tentatively key to Holocentropus, although I can't make out the anal spines in Couplet 7 of the Key to Genera of Polycentropodidae Larvae nor the dark bands in Couplet 4 of the Key to Genera of Polycentropodidae Larvae, making me wonder if I went wrong somewhere in keying it out. I don't see where that could have happened, though. It might also be that it's a very immature larva and doesn't possess all the identifying characteristics in the key yet. If Holocentropus is correct, then Holocentropus flavus and Holocentropus interruptus are the two likely possibilities based on range, but I was not able to find a description of their larvae.
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.

They fasten red (crimson red) wool around a hook, and fix onto the wool two feathers which grow under a cock’s wattles, and which in colour are like wax.

Nice shots.. Are they on Walnut, John? They look that way to me.

On Walnut, down on the fist significant bend below the bridge on Old Sterrettania Rd, there's a small trib that comes in from the WSW (I think, anyhow left bank as you face downstream..) and falls off a 6 0r 7 foot high shale ledge. Some of the most beautiful winter pics I've taken in the entire watershed were there. This was many years ago, when I was living on the ancestral homestead in the area.

At the time (this was in the 70's and 80's), Walnut Creek was a "Second Tier" (moderate priority) candidate for State Scenic River designation.
30 years later with a casino on the headwaters and pretty much the entire watershed above PA 832 developed, I would imagine its no longer a candidate for this designation. But in its day (and still now, in a scattering of places..) it and much of Elk as well really were pretty places, unique in Pennsylvania..

Nice pics!
