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

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.

Was reading an article on brook trout which said that brookies most often feed on the bottom.

Is this true in your own experience?

Pretty broad statement there. On my local streams in northern michigan, I have caught most brookies on nymphs, especially the bigger ones, I have caught some small guys on drys like an adams, never any bigger than 8, maybe its just my luck.

It is sort of a broad statement, but it isn't (IMO) without some modicum of truth, even if it is a more comparative truth.

Here's what I mean by this:

In my experience, of the 3 species of trout/char most of us fish over in the East/Midwest, I have found that day in and day out, brook trout are the least likely to be free-rising. This is among wild populations and presumes we are not talking about fish that live (as brookies often do..) in a setting sufficiently infertile that they cannot afford to let virtually any feeding opportunity pass.

I don't think the difference in this between the species is that pronounced, but I do think it is real.
