Baetis

Tiny Baetis mayflies are perhaps the most commonly encountered and imitated by anglers on all American trout streams due to their great abundance, widespread distribution, and trout-friendly emergence habits.

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.

I was surprised how bright green this pupa is. It's chartreuse. After collecting it, I experimented with melting down chartreuse jigs and making little translucent rubber caddis abdomens on my flies. They looked good, and the trout liked them, but they weren't very durable at all. This specimen is recently deceased in the photographs.

This is cheumatopsyche female. note at the posterior end of the abdomen the two semi-rectangular plates that are distinct to the base, that is a good diagnostic for cheumatopsyche.
