This study investigated how larval and adult nutrition interact in shaping reproductive traits in male and female metamorphic insects. In red flour beetles, we found that male mating activity was affected solely by juvenile diet, whereas for female fecundity the effects of larval and adult diet interacted, suggesting that harmful consequences of juvenile malnutrition can be partially compensated for if conditions improve later in life. Interestingly, path analysis showed that diet effects on reproduction were not mediated by body size in either sex, suggesting that they act via composition, rather than size, of the adult body.
