I just had a thought (hold the press!) Is there any awareness of salmonflies in the Ozarks? I was just going through some hath charts for a river in Michigan I plan to fish soon and saw the salmonfly listed on a site. I saw one once on the Missouri/Arkansas border, but come to think of it, I've never seen it discussed or included in a hatch chart. At the time I didn't even know what it was beyond being some huge stonefly.

The bug I saw was a black stonefly with a bright orange tummy and neck, definitely a stonefly, and enormous – probably at least 2.5 inches long maybe 3. It was dead along the river bank on Spring River, either at Many Islands or Riverside I can't remember which. I can't imagine an insect living in isolation so there must be some population in that area, and if so probably in other streams.

Once while eating breakfast with Matt Tucker in Mammoth Spring, he told me about a gentleman he knew who taught him how to tie a really big dry fly out of pipe insulation foam with a white or sparkly wing of some sort. Matt said it caught him fish in cold months when nobody would think of using anything like it. The description, now that I think of it, was pretty much like a ginormous stonefly. It wouldn't be a huge leap to compare it to the fly below. Are there Salmonflies in the Ozarks? Why is this never brought up?
