I think you mean imago (spinner to you and me).
Sure. I go for a tiny "absent" head and call it the neck of the insect, with the hook eye being the prominent insect head. Problem solved...Now, in tying, most tiers (myself included) will say: "tie off a neat head".
Anyway, what I am trying to figure out is: Why do we tie off a neat head vs. something that looks similar to the insect's head (eyes actually)?
Has anyone else wondered and, if so, what is your conclusion.
Cheers,
