Huge swarms of mosquitoes aren't actually hanging out; they’re just a bunch of loners who all follow the same 'go outside at sunset' rule.

The Takeaway
It was long assumed that the complex, looping dynamics of swarms required mosquitoes to coordinate with one another. This study shows that individuals simply reacting to environmental cues like light can recreate the entire collective behavior without any social interaction at all.
From the abstract
Swarming is a widespread collective behavior in animals, often thought to emerge from complex interactions among individuals. Here, we show that mating swarms of malaria mosquitoes can emerge from simple behavioral rules with minimal interaction between individuals. We analyzed two published experimental datasets with three-dimensional flight tracks of Anopheles coluzzii mosquitoes swarming above a visual marker under simulated sunset conditions. We found that individuals alternate between strai
