abstract：:Cuticular colour in the mealworm beetle (Tenebrio molitor) is a quantitative trait, varying from tan to black. Population level variation in cuticular colour has been linked to pathogen resistance in this species and in several other insects: darker individuals are more resistant to pathogens. Given that cuticular col...
