Mosquitoes can be bad news. Beyond their infuriatingly itchy bites – something I'm all too familiar with – these pests spread diseases that kill over 770,000 people worldwide every year.

In the fight against mosquitoes, understanding more about how these tiny flying vampires find their human blood meals could be helpful in designing better ways to defend against them. To that end, Georgia Tech researcher David Hu sent his student into a room with 100 mosquitoes. After recording "more mosquito flight data than had previously been measured in human history," his team was able to figure out how mosquitoes move in response to various cues.

Can you guess which part of a sacrificial grad student insects ended up concentrated around? For a visual answer, check out Hu's animation of mosquitoes' flight tracks made up of flybys, double takes and spirals.
