I commented elsewhere, but look up "Insectothopter". Nefarious orgs like the CIA seem to love symbolism, so I'd imagine there's some connection between embedding themselves in public and private research and being "flies on the wall".
Yeah, I was thinking also that it could be related to some kind of "fly on the wall" symbolism. I am just wondering if it is somehow a more general level symbol in the context, not just for the CIA or in the US. Considering the CIA Labs for example, they probably do a lot more stuff than just develop dragonfly type drones, so why put the dragonfly in the logo. But maybe the "Insectothopter" project and similar ones have just been so significant projects for them in the past that they want them to be remembered.
