Thanks guys.I have no ideal what these imitate in the insect world but the fish sure seem to like them.I usually fish these around brush piles or partially submerged trees.Shady spots are the key.Usually I can fish them as deep or shallow as I want to and still catch fish.I recently had one tied as a dropper behind a foam bug and caught a LMBass on the foam bug.What a surprise.
Seems I am always trying to tie something new or changing a pattern to try for myself.They're not always pretty and dont always work but you dont know if you dont try.
