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.

Here I was unsuccessfully trying to find some lake-run fish that would have been stopped by the impressive barrier in the background. I didn't see any fish. From Toughannock Creek in New York
I cross a small river after an unsuccessful attempt to find some fall-run landlocked salmon. This picture was taken shortly after another very nice wider picture of the same spot. Photo by Elena Vayndorf. From Toughannock Creek in New York

Many Finger Lakes tributaries have impressive waterfalls, but this is one of the best. The plunge pool is extremely deep and often holds nice fish. From Salmon Creek, Ludlowville Falls in New York

The unique geology of the Finger Lakes region of upstate NY created this waterfall, pictured here during a drought that reduced the flow to a trickle. From Toughannock Creek in New York
This waterfall is less than half a mile from the Cornell University campus. From Fall Creek, Ithaca Falls in New York

On-stream insect photos by Troutnut from the West Branch of the Delaware River in New York

A thick mating swarm of Tricorythodes mayfly spinners hovers the West Branch of the Delaware near Hale Eddy one early fall morning. View the picture full-size and you'll be able to make out the wings and tails on most of those little white dots. This was one of many such clouds visible all up and down the river. The mayflies were impressive, but the trout did not hold up their end of the bargain -- there was not a rise in sight. From the West Branch of the Delaware River in New York
