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.

A hairy mayfly nymph. This gangly, odd-looking nymph is from the rare species Ephemerella septentrionalis

This is surely the most distinctive-looking species in Ephemerellidae. I like the rugged, spindly look. If mayflies made movies, Penelomax septentrionalis would probably play the supervillain.

Maybe I should take a break and get something to eat.

Jason,

The underwater photos are unreal. What sort of lens are you using on that camera? It is just now occuring to me to ask how many of your pictures on this site are taken through a scope and how many are taken with just a camera?

Jason, these are the first photos of septentrionalis I've seen--very cool! I've been meaning to discuss this species with Greg Hoover, but I probably won't have a chance to do that until mid-June. I'll be sure to share whatever I learn.

Almost all my photos are taken without a microscope, but I do have a very specialized macro photography setup. The "underwater" photos in specimens like this one are actually not underwater, but staged in a tiny aquarium I created to take more natural-looking pictures than my usual white-background ones.
