That last one looks REAL CLOSE to the "Stickbugs" i spoke of up there^^^^^ If you all read what i wrote closely you'll see that i don't say they won't eat them , I say they don't eat them. What i mean is that when they , the stickbugs , are piled up in the eddies in bunches , i've never seen a trout go in there and actively feed from the mass of readily available food , but , when they are ready to hatch/emerge , i'm sure their behavior changes and probably the color , when they are in that pre emergence stage they signal something to the fish like maybe vulnerability or better taste or something and at that stage the fish DO eat them. If someone can show me absolute proof that they feed on them when they are in piles in the slackwater eddies , probably the most vulnerable stage of their life , i'll eat my fishing hat. Sandfly.....the more i look at that last one the better it looks , it's an almost exact imitation of what they look like in that stage of life but..........have you ever seen a trout or a fish of any kind go in the eddies in the piles and actively feed on them? I think that right before they hatch , when they start to move around and get ready to head up top , a switch goes off and the fish eat them. I can't explain what i mean any better than that but as an example , hellgramites , if you find them in the winter months up higher on the bank , out of the water maybe under a log. In that stage the fish will not bother them. They must taste bad or not provide enough nutrition or something. If you find a hellgramite under a rock out of the water in the winter months , try it , you'll see what i mean. Then go back and find one that is in the water in the same area , put it on and BANG. I'm not a scientist i go from what i've observed and learned from years of watching water and fish. The next time you are around when they stock trout , take a bucket and put it in an eddy that is loaded with stickbugs and watch them , even stockies don't eat them in that stage.
