I might very well be wrong about that, my knowledge of English idioms can be lacking at times.
However, in my experience bees are attracted to sugary material like honey even though they themselves make it. And a Google image search returns many results as well: http://images.google.com/images?q=honeypot+bee
Not to skew your point because indeed bees are attracted to honey but that image search has less meaning as many honeypots have bees on them while traditionaly bears are shown as being attracted to honey and therefore honeypots.
