English: Diffusion of string pulling behavior through the social network of Colony 6 (bout n = 189). Nodes represent individual bees. Lines indicate that two bees interacted at least once. Thickness of lines represent total number of interactions between two individuals—one interaction equals one point line thickness, and each interaction increases the line thickness by one point. Size of nodes indicates number of interactions of that individual bee with any other bee—each interaction increases the size of a node by 15% of the original size (3% of the plot width). Color represents experience (learning “generation”) of that bee: prior to any experience nodes are grey. After a bee interacts with another bee for the first time in the foraging arena, its node turns white. The “seeded” demonstrator, pretrained to string pull is yellow and at the twelve o’clock position. Once a bee learns to pull a string, its node turns from white to another color: orange for a first-order learner (interacting with the seeded demonstrator or lower order bees); pink for a second-order learner (interacting with first-order or lower-order bees); and blue for a third-order learner (interacting with second-order or lower-order bees).
