Salmonflies
Pteronarcys californica

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

I caught several wild and colorful 8-9 inch brook trout in the clear little pool below this waterfall.

Dorsal view of a Skwala (Perlodidae) (Large Springfly) Stonefly Nymph from the Yakima River in Washington

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.

Ecdyonurus criddlei (Heptageniidae) (Little Slate-Winged Dun) Mayfly Nymph from Kintla Lake in Montana

This is an interesting Heptageniid mayfly since in western Montana it is only found in cold lakes, especially those in Glacier National Park.

Hi all,
These specimens are in great shape!

the lower nymph in this photo is definitely not E. criddlei, but E. simplicoides. E. simplicioides has that distinctive color pattern with the pair of rectangular pale markings on tergum 4 and no median markings on the other terga.

The upper specimen is probably E. criddlei, but seems to have more extensive pale markings than specimens from further west.

cheers,
Jeff
