Ugly Fly

About a year ago, my mom was visiting and asked for a demononstration on fly
tying. I grabbed the first scraps I found on my desk and tied this. Size 8
Mustad 3261, peacock for the tail and body, metallic silver thread, and
small black mono eyes. I had no intention of using it, but it ended up in
one of my boxes anyway. The rainbows and brookies loved it. Could anyone
tell me why fish might like this monstrosity? I don't even know what it
could be classified as. It floats like a dry until it gets chewed, then
fishes almost like a wet. Any thoughts?
