Megjegyzések:	Most studies on animal personality evaluate individual mean behaviour to describe individual behavioural strategy, while oftenneglecting behavioural variability on the within-individual level. However, within-individual behavioural plasticity (variationinduced by environment) and within-individual residual variation (regulatory behavioural precision) are recognized as biologi-cally valid components of individual behaviour, but the evolutionary ecology of these components is still less understood. Here,we tested whether behaviour of common pill bugs (Armadillidium vulgare) differs on the among- and within-individual level andwhether it is affected by various individual specific state-related traits (sex, size andWolbachiainfection). To this aim, we assayedrisk-taking in familiar vs. unfamiliar environments 30 times along 38 days and applied double modelling statistical technique tohandle the complex hierarchical structure for both individual-specific trait means and variances. We found that there are signif-icant among-individual differences not only in mean risk-taking behaviour but also in environment- and time-induced behaviouralplasticity and residual variation.Wolbachia-infected individuals took less risk than healthy conspecifics; in addition, individualsbecame more risk-averse with time. Residual variation decreased with time, and individuals expressed higher residual variation inthe unfamiliar environment. Further, sensitization was stronger in females and in larger individuals in general. Our results suggestthat among-individual variation, behavioural plasticity and residual variation are all (i) biologically relevant components of anindividual's behavioural strategy and (ii) responsive to changes in environment or labile state variables. We propose pill bugs aspromising models for personality research due to the relative ease of getting repeated behavioural measurements
