This specimen resembled several others of around the same size and perhaps the same species, which were pretty common in my February sample from the upper Yakima. Unfortunately, I misplaced the specimen before I could get it under a microscope for a definitive ID.

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 (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
1 Picture
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. Female Caenis (Caenidae) (Angler's Curse) Mayfly Dun from unknown in Wisconsin
