Hex Mayflies
Hexagenia limbata

The famous nocturnal Hex hatch of the Midwest (and a few other lucky locations) stirs to the surface mythically large brown trout that only touch streamers for the rest of the year.

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.
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.

I don't know how many of you guys knew about this (probably everyone but me!), but the USGS recently began production of enhanced topo maps. They've currently mapped about half the states and are at varying degrees of completion with each. They've released each 7.5' x 7.5' quadrangle in PDF format using layers to show different types of data (added to this most recent release for the first time is a hydrographic layer!). You can turn on or off each type of layer with a simple toggle. The quadrangles are available for free download. I found they are each 10-20 MB in size. There is a toolbar you can also download (called TerraGo) that will enable you to interact with and personalize each map by marking spots, making notes, measuring distances and areas, and even track positions using your GPS. This seems like just the sort of tool a flyfisherman would find really useful. I'm pretty excited about it - Pennsylvania just got finished! Check it out here:
