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.

As far as I can tell, this species has only previously been reported from one site in Oregon along the Columbia gorge. However, the key characteristics are fairly unmistakable in all except for one minor detail:
— 4 small yellow spots on frons visible in photos
— Narrow occipital spinule row curves forward (but doesn’t quite meet on stem of ecdysial suture, as it's supposed to in this species)
— Short spinules on anterior margin of front legs
— Short rposterior row of blunt spinules on abdominal tergae, rather than elongated spinules dorsally
I caught several of these mature nymphs in the fishless, tiny headwaters of a creek high in the Wenatchee Mountains.
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.

Four senior fisheries scientists, including the executive director of the American Fisheries Society and my dad, have just published an editorial in multiple newspapers about right-wing extremist governor Scott Walker's efforts to severely diminish Wisconsin's fisheries research capabilities. It's a must-read for anyone in Wisconsin, and perhaps nationally if Walker runs for President.

I have, up until this time, kept this to myself, but in light of the ever increasing divisiveness which seems to be sweeping across this country I think it’s time to share. Let me first of all state that I do not have one of those string of consonants which I can attach to my name. So if you are looking for “scientific proof” you can move on now and refrain from wasting time.

(1): Can fish, more specifically “trout” react emotionally to a stimulus?
(2): Can trout be further classified into political preference through a reaction.

For the last seven years I have traveled across the country trout fishing and as noted earlier in this thread I have had success in the Democrat controlled states using
The Obama Fly. However, during this same time, I have given great thought, study and experimentation into my “RIGHT WING vs LEFT WING” theory.

First I think it would be helpful if we could come to terms on a few things I think we, as a whole, can agree with.

  • During a hatch trout are feeding.
  • It is generally accepted that the better we “match the hatch” the better our chances of catching fish.
  • During those non-hatch times trout are considered opportunistic and we often employ a “stimulator”.

My observations:
OK, so in those states which the government is controlled by a majority of Democrats the Obama Fly out performed by a huge margin as opposed to those states controlled by a Republican majority. Those fish fed on the Obama Fly and loved it. These trout are left leaning. Now this does not mean that there is no right leaning trout in those states it just means that they didn’t fall for the bait. I suppose one could argue “coincidence” that the Obama Fly was more effective in the Blue states but ponder this:

I tied up dry flies all matching except for one thing. Each fly contained only one right wing or one left wing, other than that, identical. These flies were not fished during a hatch because during a hatch the fish are feeding and all bets are off. These flies were fished as a stimulator during those times when the fish are said to be opportunistic. Beyond all doubt I found that in the “Blue” states the right winged flies were attacked by a vast majority and in the “Red” states the left winged flies were attacked by a vast majority. Yes you read that right.

Now obviously the next question is why. I think it’s the education these fish are getting in the nurseries.

When asked what I just caught that monster on I showed him. He put on his magnifiers and said, "I can't believe they can see that."
