Best guess at this bug. Smut (Simuliidae)

Kansas city Posts: 16	Fished the Niangua River in central Missouri. I have rarely seen surface or in the film action over the years. Yesterday, 9 AM, 51 degrees F, overcast skies, the rainbows went wild on these. I had seen several black flies about, but found no takers of the dry. Finally hooked two on a BWO dry, go figure, and persuaded one of them to show me what they were eating. Pictures attached. Any confirmation? https://pauldavid.smugmug.com/Bugs/i-ggdDd2n

Fenton, MI. Posts: 51	Looks like Black (aka Mothers Day) caddis but there is a hint of olive in 2 of the bugs so maybe Rhyacophila (green sedge) ???? :-)
