True Dave. And it was illegal to own any. BUT one demented scientist kept a few and discovered that they not only communicate with each other and work in teams but were capable of communicating with humans. When there were enough of them, they flew in formation (Yes they could fly - like NYC waterbugs) and spelled out "Hello" quotation marks and all. Kind of like malevolent Charlottes (who for non-readers spelled out messages in her webs). Of course, they were off and running again and burned the above mentioned scientist to death just for the fun of it before destroying the world. Anyone have a copy of this classic? It warrents re-reading.
