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.

Yep. Presence of a coxal process on the foreleg and a deep irregular notch on the frontoclypeus differentiate the Little Black Caddis from the very similar looking Dolophilodes (Winter Caddis).

When asked what I just caught that monster on I showed him. He put on his magnifiers and said, "I can't believe they can see that."

I have to ask.

Would you be willing to share how you took and what equipment you used to get these stunning images?

BTW I am currently writing a grant for my Career and Technical high school for photographic equipment for macroinvertebrate pictures and study.

Great photos, as always, Eric.

Does anyone tie and fish imitations of this bug? I used this Vimeo video to tie some, but have yet to fish them. When and where have folks had luck with this fly, if any?

Jeez, I posted those photos last March. Thanks Gentlemen!

Ed, my setup is pretty basic. I use a small aquarium (1"x 2") that I made from acrylic sheet that I cut to size and glued together. Lighting is a fiber optic microscope light. Camera is a Nikon DSLR with a 105mm f2.8 lens. And a tripod.

Thank you for the information.

It looks like you painted the back of the aquarium with black paint. Am I correct? Did you paint it on the inside of the tank?

What kind of glue did you use? Silicone or ???

Thank you again.

Are there any worthwhile tutorials on the web? I have not found one yet.
