I recall there being a rather good version of "The spider and the fly (http://www.amazon.com/exec/obidos/tg/detail/-/0689852894/qid=1122216467/sr=1-33/ref=sr_1_33/104-8948012-7639138?v=glance&s=books)" by Tony diTerlizzi. It's just the old poem put to illustration, but clearly, the spider stands out as a villan. There are a few lines that I recall being slightly sexually suggestive, but not in such a way that you can't convincingly pretend that they're not.

And it's Tony diTerlizzi, so there's no doubt that the illustrations are fantastic.
