Insect personality: what can we learn from metamorphosis?

subject

description

6 pages; International audience; Ontogeny of animal personality is still an open question. Testing whether personality traits correlated with state variables (e.g. metabolic rate, hormones) and/or life history traits, and which ones are involved, requires more empirical studies. Insects with metamorphosis represent a good opportunity to tackle this question. Because of the various degrees of internal (physiological, nervous) and environmental changes linked to metamorphosis they allow testing whether these modifications drive consistency in personality traits between immature and adult stages. In this review, we establish general predictions for the effects of metamorphosis on personality in insects with complete or incomplete metamorphosis and suffering from a strong or weak niche shift after metamorphosis. We then reviewed the still rare empirical literature and discuss future research axes.
