The winter is usually when insects die or go into a state of paused development, but for tiny specks on the white snow called snow flies, it's time to run around, find a lover and make baby snow flies. Neuroscientist
John Tuthill has been studying these creatures since he first came across them in 2016. He's found that not only can they survive in the cold, but if one of their limbs starts to freeze, they can self-amputate and pop it right off. That buys the snow fly time to find a mate and make sweet, sweet snow fly love.
