This research discovered two new species of fungi in Thailand that parasitize insects. One species infects flies while the other targets beetle larvae. The study provides detailed descriptions of these fungi and confirms they are previously unknown species through both physical examination and DNA analysis. This research contributes to our understanding of fungal biodiversity and host-parasite relationships in tropical ecosystems. Impacts on everyday life: • Helps track and understand biodiversity in tropical regions • Provides insights into natural pest control mechanisms • Advances our knowledge of fungal evolution and adaptation • Could lead to development of biological pest control methods • Contributes to conservation efforts by documenting species diversity
