Table 1. Results of the ANOVAs comparing the interaction rate with ants and mimics or with ants only before and after the addition of mimics, see also figure 3 A,B.

¹Colony differences result from differences in overall interaction rate and not from differences in how they responded to the mimics. Trends of the response were the same in direction and significance for both colonies.
