Pteronarcys californica

The giant Salmonflies of the Western mountains are legendary for their proclivity to elicit consistent dry-fly action and ferocious strikes.

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.

Female Stenonema modestum (Heptageniidae) (Cream Cahill) Mayfly Spinner from unknown in Wisconsin
This one was collected in in association with this male. It looks quite different, but that's often the case between spinner genders.

Here's a goofy picture of a Caenis dun falling off the back of a leaf, never to be seen again.  These mayflies are very tiny and fragile, and very hard to capture and photograph without damaging. This little dun hatched from the nymph in a tub of nymphs while I was picking through for aquatic specimens to photograph... I grabbed the leaf it hatched onto and tried to take some pictures but it got away after about half a picture.
