Pteronarcys californica

The giant Salmonflies of the Western mountains are legendary for their proclivity to elicit consistent dry-fly action and ferocious strikes.

This Skwala nymph still has a couple months left to go before hatching, but it's still a good representative of its species, which was extremely abundant in my sample for a stonefly of this size. It's obvious why the Yakima is known for its Skwala hatch.
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.
Troutnut is a project started in 2003 by salmonid ecologist Jason "Troutnut" Neuswanger to help anglers and fly tyers unabashedly embrace the entomological side of the sport. Learn more about Troutnut or support the project for an enhanced experience here.

This fish almost got me into the coveted "20/20 club."  It's a 20 inch brown caught on sulphur-flavored Galloup's Cripple tied on a size 18 3X-fine dry fly hook.  It's also my biggest fish to date from the Catskills.

This is a common sight on the large Catskill rivers in early May, a mother goose guarding her nest.  They like to nest on midstream islands where anglers are prone to walk from one fishing spot to another, and they do not back down.  This one was hissing at me and I didn't want to get any closer.

On-stream insect photos from the West Branch of the Delaware River

Many beetles of this species were jumping around the rocks like popcorn on a mid-April afternoon.  I'm sure they end up in the water for the trout at times.

I didn't manage to collect a nymph, but here's the hollow shuck left over from an emerged dun, showing the basic pattern of the nymph.

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.
