Is there anything that is off limits to our fish as far as bugs go. Venomous, stinging creatures maybe not so much, but earwigs, grasshoppers, and caterpillars seem to be a big hit.
I'm no expert, but I've spent a good deal of time fishing. Many of the lures we make and use have hair all over them to simulate the "real deal". In my opinion, some cilia will not bother fish. On the contrary, they may find it appealing! No science, just info based on my experiences.
