Salmonflies
Pteronarcys californica

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

This one was surprisingly straightforward to identify. The lack of a sclerite at the base of the lateral hump narrows the field quite a bit, and the other options followed fairly obvious characteristics to Clostoeca, which only has one species, Clostoeca disjuncta.
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.

Hi again,

in the web I found the pictures of male genitalia of P. ocellifera and semifasciata, and I think that I also have some males of ocellifera. But what is this one?

If this is a North American phryganid I could propose either P. ocellifera or P. postica but that would mean that most of the parts are highly retracted. It doesn't seem likely that these two appendages (presumably the lateral arms of the 10th?)would be so obvious without some of the other appendages being visible as well. It just doesn't look right.

try a caudal and/or dorsal view if possible.

Compared to P. ocellifera dorsal appendages are missing, they are very visible in my 3 ocellifera specimens. But I have 3 more similarly constructed male genitalia (in those specimens the forewing is darker than in ocellifera). I'll try to make more photoes.

Whoa, and I thought Taxon could post up some racy pics. You caddis guys all must have dirty minds.

OK, just kidding! And mostly to pick on Roger some, who missed the latest round of razzing on this site. Auction me off, indeed!

In all seriousness, I am in awe of anyone who can identify caddis. Until I'm retired and have lots of time, I won't even pretend to begin to try.

Hi Louis-

Upon seeing this thread, and before anyone had responded to it, the first thing that crossed my mind was, oh oh, this will certainly exceed Louis's threshold for specificity.

Best regards,

Careful what you say about us taxonomists. After all, once the fisherfolks started looking at fish food I think they stepped up from fish-squeezing to bottom-grabbing. And that photo is not even of the real parts :)
