Please make sure it is specific to mosquitos and does not attack other insects.

Insect populations worldwide are experiencing significant declines in both abundance and diversity, with several studies reporting reductions ranging from 40% to 75% over recent decades. Estimates suggest that 5%–10% of all insect species have disappeared in the last 150 years, and some global meta-analyses indicate terrestrial insect populations are declining by close to 9% per decade.

From the linked Hackaday article:

> If you don’t want to kill flies, wasps, bees, or other useful pollinators while eradicating the tiny little bloodsuckers that are the drone’s target, you need to be able to not only locate bugs, but discriminate mosquitoes from the others.

> For this, he uses the micro-doppler signatures that the different wing beats of the various insects put out. Wasps have a very wide-band doppler echo – their relatively long and thin wings are moving slower at the roots than at the tips. Flies, on the other hand, have stubbier wings, and emit a tighter echo signal. The mosquito signal is even tighter.

Fascinating engineering! Doesn't seem like it would be possible but it apparently is. There's also more visuals at about 17 minutes in the video embedded in that article, the signatures seem fairly distinct.

Don't want to underestimate how disastrous this could be for other insects. Even ignoring the impact on them, the impact on our needs to maintain pollinator populations.

I mean.. if they venture into human indoors they are already doomed in the first place. Not much scope of proliferating in such an artificial environment.
