The magnitude, direction and symmetry of intraguild predation (IGP) between the developmental stages of the aphido- phagous Harmonia axyridis Pallas and Coccinella undecimpunctata L. were characterized and compared. Mobility and body weight were the main factors affecting the magnitude of IGP. H. axyridis was more often the predator than C. undecimpunctata and eggs the most vulnerable developmental stage. There was significant asymmetrical IGP on eggs by the second and later, and fourth larval stages of H. axyridis and C. undecimpunctata, respectively. Asymmetrical IGP of pupae was only recorded for the fourth larval stage of H. axyridis. There was no IGP between adults, but larvae of both species attacked heterospecifics. The best model of the relationship between rate of predation and the dif- ference in the body weight of IG predator and prey differs for the two ladybirds. A small difference in the body weights leads to a marked increase in the rate of predation in H. axyridis but not in C. undecimpunctata. In asymmetrical combinations, increase in body weight of the intraguild predator did not significantly increase the rate of predation. Mobility and body weight were not the only important parameters involved in the symmetry of IGP. Aggressive behaviour of H. axyridis negatively affected the survival of C. undecimpunctata.

• Defining invasiveness and invasibility in ecological networks (2016, background): “These interactions generally favour H. axyridis, though interaction strength and even direction can be influenced by the life stage of the interacting species (Felix and Soares 2004) and the environment (Gardiner et al. 2009).”
• Intraguild predation of immature stages of British and Japanese coccinellids by the invasive ladybird Harmonia axyridis (2008, unknown): “When IGP between larvae does occur, it is usually the larger that attacks the smaller (Dixon 2000; Felix and Soares 2004).”
• The harlequin ladybird, Harmonia axyridis: global perspectives on invasion history and ecology (2016, background): “Despite the competitive advantage of H. axyridis against the native C. undecimpunctata (Felix and Soares 2004; Nóia et al. 2008), it is apparent that Azorean habitat characteristics and the high feeding rate of H. axyridis are hampering its invasion.”
