Pteronarcys californica

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

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.

Everything seems consistent with P. biloba, the "Knobbed Salmonfly." Unlike dorsata, it is usually found in small streams and headwaters where it is a real mouthful for the little trout. Typical salmonfly nymph ties tend to be likewise, so I usually choose to imitate the younger, smaller generations of nymphs.

Thanks. I've added a page for P. biloba with that information and changed the specimen's ID accordingly.

What's your source for the information? I still need to find a good source on stoneflies. I haven't tried hard yet since I've been focusing on mayflies, but it would be good to know where to start.

Unfortunately, I'm not aware of a really good, up-to-date angler's book on stoneflies. The species I've identified today are ones I know well from personal experience.

I like Stoneflies for the Angler by Leiser and Boyle (Knopf, 1982 and Stackpole paperback reprint, 1990). It was accurate and well-researched for its day and is a good general angler's reference; but it lacks any systematic keys. There's also an Arbona stonefly book that I haven't seen or read.

And to answer your question from the other thread, I haven't come across a recent species level description of Epeorus that would be of any help.
