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.

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.

I think the formal name is Brachycentrus Appalachia. In the Western Catskills it is called an "Apple Caddis".

The colors and wing shape all look about right for that hatch, but I don't know if they're found as far west as Wisconsin, and there are probably some other green Brachycentrus species, too. But I would guess it is a close relative, at least.

Some more caddis pics for you fellas... Gannoms were definitely one of the three or four caddis on the river...

Really cool, thanks for posting! Were the fish looking up? I almost came up your way today looking for rising fish. Last weekend I saw a lot of hendricksons, and the fish went bonkers for 30 mins, but then just shut down. I'm just beginning my journey to figure out the bugs up there. I think I need to explore a few new rivers. I find myself always going back to one.

I was out on the Pine a couple of days ago, and saw a fair number of Hennies, and some Red Quills (not as many), and a couple of different caddis species, both grayish, like a #12 and a #16. Not major numbers though, didn't really see any fish rising. And in one of my favorite holes, there were two steelies swimming around scaring the residents, and one that had a big nasty white scar down it's back came and sat right next to my left foot, could have stepped on him...I got three tiny rainbows that were smaller than some of my aquarium fish and a couple of 9-inchers, who both took a #12 Royal Wulff and did some jumping for me. Funny, as many Hennies as I saw on the water I didn't get much reaction to an imitation. Nothing big, but I have started my trout stream season at last.

And LOTS of blackflies already! In my face the whole time I was fishing, yet not a lot of other insects, saw some flies and a few butterflies on a blooming willow tree. No wildflowers there yet, either...we are still behind the curve around here.

No matter how big the one you just caught is, there's always a bigger one out there somewhere...

The river isn't what it used to be, the high water temps or flood or both took its toll on the trout. It is recovering, but slowly.

Jason, here is a photo of our buddy Frank Pratt fishing below me. He is fun to fish with or just to spend time with!



Amazing to catch this nice brookie about a mile from a cool feeder creek...

Thanks, it is a Sony HD something, not sure any more and the writing is worn off. It is waterproof too. I try to buy point & click cameras that have good quality macro capability. Outdoor photos for the web are so easy to get today, even on your iPhone or tablets, but macro is a different animal. If the camera doesn't have special macro settings I wont buy it. I set it on macro and take lots of pics, hoping one or two come out decent.

I have a quality Canon DSLR but I wont carry it around on the river. I have a tendency to hike all over the river and fish some really tough spots. So if I take a tumble in the river I don't want to ruin a good DSLR camera. so far no tumbles but I am not a limber as I used to be. :-)

Nice pics John! Is that down below town somewhere?

Looks like Frank is enjoying retirement.

I caught a brookie downstream of town quite a ways two weekends ago. The first year I fished up there was the best. More big fish for sure. I've been catching decent numbers of medium sized fish though, so hopefully in a few years. The bugs are still strong as far as I can tell, but I have only been going up for 4 years or so.

I'm curious did the fellow in the right side of the picture row through in front of the wading angler? On the rivers I fish in New York if a guy does that and the wading angler can reach with his cast to where the boater rows that is asking for a confrontation. I wouldn't hesitate to ask a boater to please go behind me. If he chooses otherwise don't be surprised if my cast accidentally goes over his boat and if the hook happens to get impaled somewhere....oops, sorry.

Matt, they went behind Frank. In another section I had a canoe that went in front of me but I had stepped back towards the bank while I was changing my tippet. They went right through the run which was the deepest water. I wasn't happy about it but I doubt the couple in the canoe knew anything about trout fishing.

Hey guys, havent posted here in a LONG time, good to be back!

I dont know much about the trout rivers in the far north of the US, but always a pleasure to see that Brookies are being caught the bigger water, not just the brooks and feeder streams. I am pleased to say that Brook Trout are appearing in greater numbers in the Neversink in the Catskills as well. First brookie I ever caught there was 2 weeks ago and Ive talked to 2 other guys catching them as well, great sign!
