Dr. Mohamed Babu from Mysore, India fed ants food-dye filled sugar water, photographing these lovely patterns of ants filling their crops (also known as “social stomachs”) with the bright colors, and making different color combinations when they change droplets.
Beautiful stuff, more info here from a (rather strangely-written) Daily Mail article. Doesn’t this make you wish you had a translucent social stomach?
