Trait-based approaches, particularly those focusing on behavioral traits, have become increasingly important in ecology. However, empirical studies addressing behavioral trait variation in insects remain comparatively scarce. To address this knowledge gap, we investigated the behavior of six wild-living ground beetle species for which no behavioral data have previously been reported. Using standardized behavioral measures, we found that in species occurring in their preferred forest habitats, behavioral traits related to activity, exploration, boldness, and risk-taking showed weak or limited temporal consistency. In contrast, in species inhabiting modified forest habitats, behavioral traits exhibited pronounced and repeatable individual differences, were intercorrelated, and formed behavioral syndromes. Moreover, half of the studied species showed sex-specific differences in personality, reflecting drivers related to reproductive roles and investment. Overall, our findings emphasize that animal personality and behavioral syndromes in ground beetles are not universal species-level properties but emerge from the interaction between intrinsic traits, and sex-specific strategies, underscoring the importance of considering ecological context when interpreting individual-level behavioral variation.
