Abstract In a few species, males face a choice between mating and/or cannibalizing females. Various factors influence this decision, making it essential to decipher the role of male behavioral variation. In particular, aggressiveness has been proposed as a trait under sexual selection that may also increase the incidence of cannibalism in such systems.

1 Introduction Stable and consistent patterns of behaviour through time and/or across contexts, commonly referred to as animal personality (Dall et al. 2004; Réale et al. 2007; Bell et al. 2009), have been shown to impact animal survival and/or reproduction across taxa (Moiron et al. 2020; Schuett et al. 2010). Personality traits, such as risk-taking, exploration or aggressiveness, can predict individual ability to access resources, such as food (Troxell-Smith and Mella 2017) or mates (Schuett et al.
