Cockroaches make me uncomfortable, but I would not say I fear them. As a kid I was the designated person in the family to deal with all manner of bugs and just whatever.
Except for whatever reason, I am absolutely terrified of moths and butterflies. I don't want to be touched by either of those ever and I don't want them inside my house. I can appreciate butterflies are pretty and colourful and all that but I still don't want them to be near me.
