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.

Some characteristics from the microscope images for the tentative species id: The postero-lateral projections are found only on segment 9, not segment 8. Based on the key in Jacobus et al. (2014), it appears to key to Neoleptophlebia adoptiva or Neoleptophlebia heteronea, same as this specimen with pretty different abdominal markings. However, distinguishing between those calls for comparing the lengths of the second and third segment of the labial palp, and this one (like the other one) only seems to have two segments. So I'm stuck on them both. It's likely that the fact that they're immature nymphs stymies identification in some important way.
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.

I bought a new raft this week (more on that in an upcoming post) and took a couple free hours to test it out in a local pond. Caught one little stocked grayling that revealed itself by rising to one of the very sporadic Callibaetis duns emerging just days before the pond freezes for the next 7 months. Winter is coming.

Even stocker grayling are pretty. I planned to keep this one for dinner if it was the first of many, but the others weren't biting and the stringer hadn't done any permanent damage, so I released it unharmed.

You need to have an imaginative mind like I have. I catch my limit last stool at the happy hr. bar all the time, and my season never ends. We just had a nearby lake stocked with grayling recently. Good pics, and nice boat.
