  1. The number of silverfish individuals differs in some colonies between the multivariate analysis of all behavioural categories and the analysis of the aggression index as some individuals did not complete the standardised number of 50 ant contacts for the social acceptance experiment as some silverfish were seized by ant workers (Table 2). Abbreviations: * = six days isolated silverfish; ** = nine days isolated silverfish
