Look at these wierd looking things...they are shucks from tiny little water striders, this is the first time i have noticed these on a river. each shuck had 4 tails...which ruled out any mayflies. Then i noticed hundreds of very little water striders in the pool. in front of me..there were no tricos or midges anywhere to be found so i hypothesized that the shucks belonged to these little striders....i caught one and compared to the shucks on the rocks...was a perfect match! Anyone know if trout eat the nymphs?
