1. In nature, hosts face shifting patterns of parasite exposure and life history trade‐offs, as they develop from birth to old age. As a result, the net fitness benefit of immunological investment can change dramatically from one life stage to the next.2. Previous work has revealed a puzzling diversity of relative immune investment patterns among juvenile and adult stages, and it is not clear whether lessons learned from one particular population or species can be generalised to wild populations, after accounting for local adaptation and other variance‐generating processes.3. In this study, we quantify larval and adult immune gene expression and resistance to bacterial infection in two flour beetle species (Tribolium castaneumandTribolium confusum) from seven wild‐derived populations.4. Our results provide a clear signal of higher infection‐induced immunological investment and resistance in adults relative to larvae, despite variation among species in immune gene regulation.5. Better characterisation of stage‐specific investment in infection resistance in natural populations can inform our understanding of life history evolution and improve predictions of disease dynamics in the wild.
