I think that there just aren't enough active users on the Wiki to really give it that community feel.
I don't see myself as any kind of expert on the monsters themselves - unless there's something that stands out as completely, and blatantly wrong, I'm really not going to say anything. I might sneak in and make a few small edits to make sure its categorized right, or that the templates are being used right, but I doubt I'll do much more than that.
At a glance, your flies, and all the other monsters on the Wiki look great - I haven't had a chance to play with them yet, I don't know that I will actually ever get that chance, unfortunately, but that should not dissuade you from posting, improving, or adding to them.

We really need a whole lot more people involved in the community, people who are going to be opinionated, and give feedback... the larger the community, the more people will give feedback.
