Tiny experiment

The Tiny Tuesday challenge provides me with a good excuse to show you some of the stuff I am playing with in the lab. Here's a prototype of a set-up I made this week, which allows the ants to choose their nest site, or between different aphids. The tubes are each connected to a box, all the ants and their larvae started in the lower right box, but they decided to move everything over night. Here they are moving their larvae.
