Blue-winged Olives
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.
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.

Closeup insects by Troutnut from Fall Creek and Mystery Creek #62 in New York

An Ephemerella mayfly. This mayfly is an adult mayfly of the imago or "spinner" stage

I collected this beautiful male Hendrickson specimen as a dun, along with a female Hendrickson from the same hatch. Both molted into spinners in my house within a couple of days.
Chironomidae (Midge) True Fly Adult from Mystery Creek #62 in New York
One of the only real benefits I've got from my rearing aquarium so far is that I've had quite a variety of midges emerge, giving me a chance to photograph these fragile little insects which are otherwise really hard to transport in photogenic form. This one recovered from being gassed and flew away before I could photograph it on the ruler, but it was very small, around 1.5mm.

This female Hendrickson spinner is in kind of bad shape, but at least now I've got some good closeup photos of one. I collected her and a male Hendrickson as duns from the same hatch, and both molted into spinners in my house within a couple of days.
