Lady bugs bite. Mrs BG reported to me she was viciously gnawed upon by a bug that wasn't very lady-like. I laughed, then "Googled" it. Sure enough, lady bugs will bite. They have no venom or irritating saliva so you're not likely to perish from a lady bug bite. Unless you're involved in some type of Stephen King horror scenario where dead lady bugs were buried on ancient Indian burial grounds. That could be bad.
