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.

Skwala (Large Springfly) Stonefly Nymph Skwala (Large Springfly) Stonefly Nymph

Dorsal view of a Skwala (Perlodidae) (Large Springfly) Stonefly Nymph from the Yakima River in Washington

This Skwala nymph still has a couple months left to go before hatching, but it's still a good representative of its species, which was extremely abundant in my sample for a stonefly of this size. It's obvious why the Yakima is known for its Skwala hatch.

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.

Female Stenonema modestum (Cream Cahill) Mayfly Spinner

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.

Female Caenis (Angler's Curse) Mayfly Dun

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.
