DARPA spy-bugs

DARPA spy-bugs are mostly flying insects,
and much-less-commonly ground bugs (insects, spiders, etcetera),
which contain delicately-implanted microelectronics,
which guide the bugs' movement (via brain electrodes) when their operator so-desires,
and which contain micro-cameras and micro-transmitters.
They are so-named becuz they were developed by DARPA-
Defense Advanced Research Projects Agency.

The implantation of the microelectronics is obviously not done by hand,
but requires advanced precision machinery.
The bugs also incorporate non-metallic conductors for some roles.

The cameras attain adequate resolution, despite their minute size,
via using a very small vision-field of adequate resolution
(the larger the vision-field, the larger the needed camera),
whereas a low-resolution broad-field camera is used for general navigation.

Such spy-bugs are available to agents within U.S. intelligence-agencies,
including but not limited to the CIA and DIA,
and possibly also one or more foreign allied agencies.
Although such spy-bugs are used for legitimit defense purposes,
they are also sometimes abused for privacy-violating purposes,
under the guise of "threat assessment", which makes this a privacy-rights issue.
