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 is one of the many shallow, unnamed lakes in the Arctic coastal plain near the Dalton Highway.

With a bit of help from the microscope, this specimen keys clearly and unsurprisingly to Hydropsyche.

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.

No fish but some beautiful scenery and a big scary (true) bug!

Yesterday I checked out another lake stocked with trout that is open all year long. I didn't catch anything and in fact saw no fish rising or anything, but it was a really beautiful place so I couldn't resist taking a few pictures. Then, while walking along the shoreline to stretch my legs, I saw this Lethocerus sp. - giant water bug - swimming along in the shallows. This thing actually came at my boot!

No matter how big the one you just caught is, there's always a bigger one out there somewhere...

Jonathon - Ahh... The ol' Toe Biters.

Go to Taxon's forum and check out the few he's got there. There's one that has an extreme close-up with his microscope of the biting parts. Or should I say skewering parts?

Trust me, I knew better than to pick the darned thing up...I collected a specimen once and they have the equivalent of probably a 16-guage needle for a mouth. Plus, there is actually supposed to be some venom involved...

Once upon a time at the University of Michigan Biological Station (a.k.a. Bug Camp), I did pick up a Ranatra sp. "water scorpion" (Hemiptera: Nepidae) without getting poked somehow. I did not try to restrain said bug, just lifted it in a handful of water. It eventually flew away, leaving me unharmed.
