Check this video out:

I don't know if this is just science fiction or something that the military is working on. Sure seems plausible and a good idea, though.
Supposedly, these bugbots would be similar to the US unmanned aerial vehicle drones, except it seems that these bugbots would have a bit more artificial intelligence involved, they would be more maneuverable and a lot smaller.
Interesting technology.
