Blue-winged Olives
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.

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.

Bob-

That is a strange one. Wish your photo had better definition. Doesn't look like a stonefly nymph to me. With the truncate (or perhaps vertical) head, and quite widely separated thoracic segment plates, it really doesn't look exactly like any aquatic insect immature I recall seeing. How long was it? Was it clinging to the underside of a submerged rock?

Best regards,
