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 view of the pipeline, the Atigun River, and an impressive sunset/rise was one of my first views of the North Slope as I came through Atigun Pass in the middle of the night.

Ephemerella mucronata Mayfly Nymph Ephemerella mucronata Mayfly Nymph

Dorsal view of a Ephemerella mucronata (Ephemerellidae) Mayfly Nymph from the Yakima River in Washington

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.

Cell Phone / iPod / iPad DIY Photo-Microscope (aka Smart-D-Scope)

A couple of weeks back I mentioned using cell phones, iPod Touch, and iPads with a $1.00 lens as a way to take dissecting microscope-like quality pictures.

I have been playing around with them and have built several different models that work. I have also used them with my high school students. (My school owns enough iPod Touch devices that I can supply one for each lab group.)

Students have taken to them like trout take to a hex hatch! Even students who are not normally engaged like the idea that something they have can take close up pictures of things that make ordinary stuff look scary.
New! I have put directions that I have written on how to build your own Smart-D-Scope for less than $8.00 at;

Thanks for sharing, Ed! I have both devices and will give it a go.
