At that distance, the “bats” should look like the “bugs”. The scale is way off. It should be a large swarm of bats and you shouldn’t be able to see the bugs until they get close to the camera. It is a cool particle simulation, though.

Doesn’t look like flying insect motion. They should be moving with natural air turbulence/wind more.

I don’t think any insects concentrate that tightly while in flight
