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.

Mites

This common name refers to only one order. Click its scientific name to learn more.

Arthropod Order Acari

These are pretty much always called Mites.
This is the only picture in the set in which the mite was alive.  I had to kill it in alcohol for the others, because it was scurrying around too much to stay in focus at the high zoom level needed to show some detail on such a tiny critter.

These tiny little aquatic mites show up in my samples from time to time. This fairly large one is only about 1mm long, so these aren't relevant to trout, but it's interesting to know that they're down there, anyway.
