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

This one seems to lead to Couplet 35 of the Key to Genera of Perlodidae Nymphs and the genus Isoperla, but I'm skeptical that's correct based on the general look. I need to get it under the microscope to review several choices in the key, and it'll probably end up a different Perlodidae.
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.

These occasionally aquatic creatures are not known to be particularly important to trout, but I have a few neat pictures.

I have these Arthropod Order Araneae (Spiders) all over my property last weekend in West Kill NY. Are they poisonous? Do they live in the creek? Are they coming out of the creek to hatch because each one had a wed and egg sacks inside. They are big! Any thing interesting or warnings about these, I'd like to know.
