I used to creek fish a lot with spinning gear as a kid. We would park ourselves under a tree that was full of those tent caterpillars and drop a worm in the pool. Almost always a strike. Now on trout creek which is on the way home from my favorite lake I sometimes stop to flick a black and brown wooly bugger in under the tent caterpillar nests with great success. I once watched as hoards of ants were traversing a stream across a thin branch. A black ant pattern just downstream of that branch was deadly.

Good article nicely told. thanks.
