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.

This one seems to tentatively key to Holocentropus, although I can't make out the anal spines in Couplet 7 of the Key to Genera of Polycentropodidae Larvae nor the dark bands in Couplet 4 of the Key to Genera of Polycentropodidae Larvae, making me wonder if I went wrong somewhere in keying it out. I don't see where that could have happened, though. It might also be that it's a very immature larva and doesn't possess all the identifying characteristics in the key yet. If Holocentropus is correct, then Holocentropus flavus and Holocentropus interruptus are the two likely possibilities based on range, but I was not able to find a description of their larvae.

My brother and I kept a few fish for dinner the other night and examined the stomach contents. There were a few insects and shrimp, but what I was most intrigued by was that about 95% of what was in their stomachs was seaweed. We were wondering if the fish consume this because they know it contains crustaceans and insects, or if the seaweed is consumed unintentionally as they consume bugs, or if they actually gain some nutrition from the seaweed. Thoughts?

I would be inclined to think they eat seaweed as a by product of eating insects and crustaceans, or because they know insects and crustaceans reside in them. This is a very interesting question though. Anyone have a good seaweed fly?

Dunno. I've seen it too -filamentous algae I believe, but not to that degree. Any idea what the plants were?

Not a clue. Probably the same stuff we kept picking off our flies. Maybe we should have left it on there. Then again, would that be considered bait fishing?

Maybe they're a vegan subspecies?
All men who fish may in turn be divided into two parts: those who fish for trout and those who don't. Trout fishermen are a race apart: they are a dedicated crew- indolent, improvident, and quietly mad.

I guess that would be considered vegan bait. AOK in some circles.
