Direct transmission of cuticular bacteria is influenced by the phenotypes of both exposed and susceptible individuals. (a) A greater proportion of pairs in which the exposed individual was bolder resulted in successful transmission and (b) transmission was more likely when exposed individuals were bolder than their susceptible colony-mates (positive values denote a bolder exposed individual, while negative values denote a bolder susceptible). (c) Transmission was also more likely when susceptible individuals had a positive body condition, i.e. weighed more than predicted based on their body size.
