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 spent more than an hour casting to several rising trout in this pool and caught only two. Its clear water and tricky currents harbor dozens of free-rising, usually very hard-to-catch fish.

This is the first of it's family I've seen, collected from a tiny, fishless stream in the Cascades. The three species of this genus all live in the Northwest and are predators that primarily eat stonefly nymphs Merritt R.W., Cummins, K.W., and Berg, M.B. (2019).

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.

Water mites are common in lakes and ponds but because they are so small they do not get noticed.These specimens are from temporary wetlands in Glacier National Park.

I've seen a lot of large red water mites in [REDACTED] Pond while snorkeling there. They must not taste good to fish, probably one reason for the red color, as they are both very obvious and swim freely thorugh the water. I did see a water scorpion (Ranatra sp.) sucking on one of them in there, though...

No matter how big the one you just caught is, there's always a bigger one out there somewhere...
