Fight club for flies

I’ve been watching a lot of fly behavior recently and it’s pretty spectacular how easy it is to imagine you’re looking at a mammal (just smaller, smellier, and with more legs.) They wander around, clean themselves off, rub their greedy little hands together, fight, and sing.

Watch the very good video above to see how these guys fight each other. It’s about work from David Anderson’s lab on aggression and tachykinin, aka Substance P.
