110471 external_news 1329735676 1475893526 Andrew Quitmeyer, a Digital Media Ph.D. student and research assistant in the Bio-tracking Lab, has created a video that presents step-by-step instructions for color-coding ants within a colony. The color-coding of a single ant is a painstaking process which involves the use of CO2 gas, a stereoscope, and a small paintbrush. The technique is useful for tracking the movement of one ant among thousands, and is in use at labs like Georgia Tech and other labs which study emergent behavior in groups of insects.
