Who said I’m building anything?
I’d like to point out for the third time the pure theoretical and idea gathering nature of this thread, if someone feels triggered or offended by the idea please just skip it

Touchy today.

Here's one: https://cosmosmagazine.com/uncategorized/mosquitoes-are-really-on-the-radar/ They were able to detect and count insects and classify them based on their wing beat rate. I'd expect the wavelength of illuminating source to be somewhere in the range of near IR (> 1000 nm) to near UV (>350 nm), basically the visible light spectrum plus a bit.

Pretty interesting

Especially since the intent was to protect people in the malarial zones - people that can barely afford running water. This was from the same outfit that wanted to solve global warming by lofting some sort of dust into near-space and reduce hurricane season with evaporative coolers in the Gulf of Mexico. All thought, no action and zero consideration for unintended consequences. Though, they did file a few patent claims.
And while we are at it, the company should have been named Intellectual Vultures, not Intellectual Ventures. But that is the subject of a different rant.

The malaria thing was to gain press coverage and it worked because you are talking about it.
The patent thing was to earn money if somebody tries to actually build it and sell in the West.
Never take anything coming from America at face value :P

No, they really thought they would be conquering malaria. I know several people involved. And the patents, maybe.
But on your last point, I've edited it to make it more realistic: Never take anything coming from America at facevalue
elektrolitr:
Hawk-Eye system used in tennis etc is said to be accurate to <4mm and is using only high-speed cameras and image processing. I think that tracking a tennis ball in a court is the same order of difficulty as tracking a mosquito in a regular size room.
The key difference would be that a ball has already a contrasting color. But, if one can't paint mosquitos, there is always option to paint the room!

Triangulating sound method works for a single target.
I doubt it would work if there are a number of mosquitoes in the room.
