Literal Surveillance Bug



So, you know how we call the Tracking Device a bug, since we all tend to speak American and are therefore too lazy to say more than one syllable?

This is what happens when a clever writer realizes that hey, maybe it actually can be a bug! A robot bug, with cameras and laser beams! Awesome! You can even replace the Sci Fi with Magic, if need be.

All of this on top of the fact that bugs themselves are rather unobtrusive, and people don't usually shriek in horror when there's just a random bug hanging around, minding its own business. As a result, they tend to be both cool and practical. It's hardly surprising that this trope appears in Science Fiction, Fantasy, and everything in-between.

This trope isn't just restricted to fiction, either- it turns out that actual beetles can be manipulated in such a way that they work as great surveillance, although full applications on this are still in the works. These studies also discredit one common appearance of this trope- robotic bugs. It turns out that they're Cool but Impractical, since making them work pretty much requires that scientists makes them as much like actual beetles as possible.

All of which gives a whole new meaning to "Fly on the Wall".

Live Action Television

 * Baikinman's team uses a spider-shaped electronic bug (ehh... right) in an Soreike! Anpanman movie (it was either Ruby no negai or Yumeneko no kuni no Nyanii). Apparently Baikinman got over his hatred of spiders when he transformed into one in Baikinman no Gyakushuu.

 * In the X Files episode War Of The Coprophages, Mulder stumbles upon a swarm of methane-powered robotic alien space probes disguised as roaches who have been conducting research on a small town in New England. Because they have a tendency to swarm over the recently-dead in order to collect samples, the townsfolk erroneously believe them to be responsible for the deaths and mass hysteria over killer cockroaches ensues.
 * Flying robotic bugs were used by Mega Corp Vex-Cor in Charlie Jade.
 * Skylar in Alphas makes these.

Literature

 * The Animorphs would frequently morph bugs for surveillance purposes.

 * Deception Point by Dan Brown has the spy bugs used by Delta Force.
 * This is part of the Palantir Ploy in Abarat--the Midnightian Royal Family has robot spy-bugs and spy-birds and spy-who-knows-what all over the place. Candy actually beats one up once, to prevent it from hurting the child of the kind lady who gave her shelter.
 * One features in the opening chapter of Roger Zelazney's Lord of Light
 * A Danny Dunn book (science fiction for '60s youngsters) has this for a plot -- the eccentric scientist invents a dragonfly that can be remote-controlled by virtual reality, and three kids get hold of it and use it for their own purposes (mostly tormenting the local bully, but also spying on crooks).
 * The clockwork "spy fly" in His Dark Materials.
 * In The Neutronium Alchemist by Peter F Hamilton, an intelligence agency is using biotech spiders to spy on a radical group. Realising what's happening the group arranges for gangs of local kids to squash every spider in sight as a game.
 * In Pandora's Star, also by Peter F. Hamilton, Paula Myo and her team use modified insects to spy past privacy shields that scramble any electronic attempts at spying.
 * In the Liaden Universe novel Fledgling, Win Ton catches an insect-like device spying on the Delgado party (though it is referred to as a "spying device" as the parties discussing it apparently do not use the colloquialism "bug").
 * In the first Star Trek Titan book, the Romulan Tal Shiar (their state intelligence agency) use tiny crawling robotic bugs to eavesdrop on a closed meeting of Romulan and Federation dignitaries. The devices are discovered only afterwards, but do prove useful in a later mission (in the next book of the series).

 * The Beetle serves this function in The Legend of Zelda Skyward Sword. Not only it allows to retrieve small items and press unreachable switches, an upgrade also allows it to carry larger objects (pots, bombs, etc.), and subsequent upgrades provide it a longer range and the ability to accelerate.

Web Comics
""I don't know what tricks they're using to find me yet… my current theory is that they've bugged my bugs.""

Western Animation

 * Mechanicalles made some of these in the Aladdin TV series.
 * The Monarch uses butterflies like this in The Venture Brothers, although you can't help but wonder why no one notices that butterflies are, in fact, The Monarch's whole supervillain theme. It helps, of course, that as far as Dr. Venture is concerned The Monarch is an Unknown Rival.

 * The Predacons in Beast Wars sometimes use these.

Real Life

 * For those interested in how this trope is being applied in Real Life, some YouTube links for your perusal.
 * Alleged first example of some kind of this trope would be CIA's project to implant a microphone and a radio in a cat (fun fact: the antenna was going through the tail). Thus created spy-cat would have been given to persons of interest as a inconspicuous gift. Then, during field tests, first ever spy-cat was run over by a car in minutes since its release, and the project was scrapped.
 * The Insectothopter, a 1970's bug disguised as a dragonfly.
