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.

This wild-looking little thing completely puzzled me. At first I was thinking beetle or month larva, until I got a look at the pictures on the computer screen. I made a couple of incorrect guesses before entomologist Greg Courtney pointed me in the right direction with Psychodidae. He suggested a possible genus of Thornburghiella, but could not rule out some other members of the tribe Pericomini.

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.

On my way to a favorite brook trout stream, I spotted several sandhill cranes in a Wisconsin farm field. From Rusk County, WI in Wisconsin

These caddisflies were thick over the water in the evening on a cold, clear northwoods lake. They were in many places on the lake, all closer to the shady shore, which also was the shore most sheltered from the wind. I'm not sure which of those features attracted them. From Lake Owen in Wisconsin

Two Phryganeidae caddis larvae fighting over a case

Caddisfly larvae of this family can easily leave and re-enters their cases. I caught two of them playing musical chairs or something with this one... funny!

Hexagenia

This is one of the earliest videos I made, and I was experimenting with a tank and background that didn't work very well.

Water Boatman Rowing

Water boatmen are excellent swimmers, and you can see here how they use their oars to push themselves through the water, a motion easily imitated by the fly fisher.

The specimen is right-side-up, but dead, in this picture. The isopropyl alcohol I used to kill it also immediately discolored it. Dorsal view of a Notonectidae (Backswimmer) True Bug Adult from unknown in Wisconsin

Here's a big water scorpion (no relation to actual scorpions). These guys are just about the most sinister-looking creatures you could find, and what's especially creepy is that they can come up out of the water and fly around, as I learned when one left my aquarium and buzzed my head while I was peeking into the microscope at a mayfly nymph.

I know most people know what a worm looks like, but when trying to tie an imitation, the memory is often a poor source of accurate color information, and a picture helps to get the right shade. One thing that surprised me in my sampling is that quite a few worms did turn up. Before I was a fly fisherman, when I used worms for bait, I always thought they were merely a tantalizing morsel and not a regular trout food, but I've since realized that there are quite a few worms that live in the sediment on a stream bottom.
