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 specimen appears to be of the same species as this one collected in the same spot two months earlier. The identification of both is tentative. This one suffered some physical damage before being photographed, too, so the colors aren't totally natural. I was mostly photographing it to test out some new camera setting idea, which worked really well for a couple of closeups.
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 have noticed a good amount of baetis nymph shucks tied with an orange antron or similar material. What do you folks think about the right color for a shuck?

Yeah, LaFontaine liked to use orange wings on his emergers - his "Theory of Attraction" working there as opposed to imitation. The mysterious success of the color orange when incorporated in flies used during hatches of olive mayflies goes back many years. It was reported by English authors at least as far back as 80 years ago, perhaps more. In my experience, sometimes it seems to help - but usually not.
