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.

This is the first of it's family I've seen, collected from a tiny, fishless stream in the Cascades. The three species of this genus all live in the Northwest and are predators that primarily eat stonefly nymphs Merritt R.W., Cummins, K.W., and Berg, M.B. (2019).
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.

Could use a little help here. I know I've got some stonefly fly nymphs in the first picture but does anyone have ideas of the other few bugs that are in these shots
I like to put a little jiggle in my wiggle to set the hook

You have some caddisflies in the bottom picture, probably Hydropsyche. The mayfly nymphs are possibly Heptagenia and the light colored cylindrical ones are members of the fly family (Diptera). The top picture is a midge or mosquito.

Thank you for the help I'm really new to fly fishing and I've been picking up every book I can but there's a lot to learn. So I really appreciate the patience that you guys have on this forum in teaching people like me how to enjoy the sport even more. I'll be sure to start putting all of my insects on white backgrounds for photography and anything else you can recommend to make this easier for me to learn and more productive for fishing.
