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.

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.

Favorite part of article:

"Dr. Peter Duelli first described this odd structure in 2004, when he observed males slowly erecting their glenofinger—but they were very shy. “When the males are undisturbed, the glenofinger can grow to almost the size of the abdomen. At the slightest disturbance (vibration, noise, shadow) it’s withdrawn.” Winterton commented, “They’re very secretive about it. You really have to set the mood for this sort of thing to happen.”

I LOVE IT!!

Yep, it's a pretty wacky world when it comes to six-legged creatures!! Of course, we are talking about Australia, home of the weirdest and most dangerous of nearly every type of venomous animal (snake, spider, jellyfish, octopus, bony fish, wasp, cone shell, etc.)...

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

Good one, but I forsee a debate a la Fontaine's caddis coming on:

Winterton’s not sure if the glenofinger inflates with air, or fills with body fluid.
