Pteronarcys californica

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

This is an interesting one. Following the keys in Merritt R.W., Cummins, K.W., and Berg, M.B. (2019) and Jacobus et al. (2014), it keys clearly to Ephemerella. Jacobus et al provide a key to species, but some of the characteristics are tricky to interpret without illustrations. If I didn't make any mistakes, this one keys to Ephemerella mucronata, which has not previously been reported any closer to here than Montana and Alberta. The main character seems to fit well: "Abdominal terga with prominent, paired, subparallel, spiculate ridges." Several illustrations or descriptions of this holarctic species from the US and Europe seem to match, including the body length, tarsal claws and denticles, labial palp, and gill shapes. These sources include including Richard Allen's original description of this species in North America under the now-defunct name E. moffatae in Allen RK (1977) and the figures in this description of the species in Italy.
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.

Hi Everyone,

Please forgive the shameless plug...

I work for FishingTV, a video on demand platform for anglers.

We've recently joined forces with a young filmmaking duo called Chalkstream fly in order to make the definitive documentary about the famous chalkstreams of England. Why are they so special - what is it about the ecology, geography and history of the rivers that results in such a lauded reputation among fly fishers?

We've launched a kickstarter to fund the film, as we want to democratise the process. We've got some amazing rewards including money-cant-buy fishing opportunities, the chance to appear in the film or take part in the editing and creative process.

For all the info, please visit the kickstarter page! https://www.kickstarter.com/projects/377649280/chalk-a-fly-fishing-oddessy-on-the-chalkstreams-of?ref=8icm5f

I usually delete this sort of advertisement from a first-time poster, but this sounds like a pretty cool project so I'll leave it. George, please come back and update this post with a reply when the film's available.

It's on other forums as well. By the sounds of it, it is legit.

Hi Troutnut, thanks for your understanding, and forgive my faux pas for barging in and advertising the project like that!

Iasgair, we sure are legit, and our campaign is going really well: we're very nearly half-way to our target of £16K, and there seems to be lots of interest in the project.

There's some really cool rewards for backers, so if you've ever fancied fishing one of these awesome rivers, or fancy yourself as the next star of fishing film and television, don't delay!

I'll definitely be popping back up every now and again to let you know about progress with the project and then with teasers and trailers and such!

Watch this space!
