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

With a bit of help from the microscope, this specimen keys clearly and unsurprisingly to Hydropsyche.
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.

Okay, Jason and Western guys what is this chartreuse midge called?



I just got back from Montana and this is the second year I have seen this midge during sunny, mid-days and some trout were taking them in the drift.

Hi John-

I suggest you contact Ethan Bright at ethanbr@umich.edu, but this one is pretty close.

John, did you tie or use anything to resemble the pupa or adult? If so were you successful?

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."

Yes, I had a small soft hackle with a lime green body that did okay. Then I tied up several parachute style dries with a chartreuse strand body material. If I saw a trout take a chartreuse midge I dropped my pattern a couple feet in front and they generally took my pattern.

The midge had a short window of effectiveness because Trico spinners shortly afterwards appeared and the trout immediately switched to the growing number of tiny spinners spread eagle in the drift.

Roger, thanks.. it is nice to see you are still hanging around here. The BugGuide midge looks almost the same and was from MT and says was photographed the end of August 2010. So close to the same time period and area.

I did find another chironomid in France that seemed similar to the chartreuse midge from the West Yellowstone area that I saw.
