Hex Mayflies
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.

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?

Paul,
The pictures don't look like a Simuliidae. The antennae of the insects in the picture is too long. They look more like some kind of caddisfly.

Yes, caddis.

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

Definitely caddisflies. Looks like some pupae and drowned adults.
