the bug books are a great idea. My 2 are older, 5 and 3 and are both fascinated by bugs except for spiders, flies and bees. I try to explain to them the good things the bugs do, like bees help flowers and they make honey, but not to bother them because they are scared of you because you are so much bigger. so they may sting you if you bother them. I also encourage them to be bug helpers. if they see a bug inside, tell me and we can put them outside so it can find its family. or if we are outside and a bug is on the sidewalk move it to a tree or the grass so no one steps on it accidentally.
