Most insects are host to diverse bacterial communities, having significant impacts on their evolution and diversity. Some symbiotic bacteria are harmful like parasites or pathogens, while other play pivotal roles by providing protective benefits. While a few systems have been well studied, our knowledge of the diversity, distribution and ecological consequences of protective symbioses is limited. The role of protective symbionts in their hosts’ inter-specific interactions, such as predator-prey, remains largely unexplored, particularly in wild populations. This project addresses this issue using chemically defended species, which rely on bacterial symbionts for defence production. Symbiotic bacteria from several chemically defended moth species is characterised and analysed for diversity and spatio-temporal distribution throughout Finland. The results will provide valuable data on how protective symbionts impact ecologically important traits and population dynamics of insect hosts
