Abstract: Understanding a species’ life history is essential for assessing its adaptability and resource trade-offs under environmental stress. Given their diversity and ecological significance, Lepidoptera represent an ideal model system for studying such adaptive responses. Under controlled laboratory conditions, we quantified the life history traits of Telchinia issoria and examined their associations with key abiotic factors—temperature, humidity, and light intensity—across all developmental stages. The results showed that: (1) the complete developmental duration from egg to adult was first quantified, establishing a crucial baseline for understanding its life history strategy; (2) the egg stage exhibited the highest survival rate, whereas the eighth-instar larval stage showed the lowest; and (3) correlations with abiotic factors differed markedly across stages, indicating stage-specific environmental sensitivity. Faster larval development may be associated with higher temperature, humidity, and light intensity; pupal development with high humidity and low light; and adult lifespan with low temperature, high humidity, and dim light. These findings advance our understanding of insect developmental plasticity, supporting more accurate population models and informing insect management and biodiversity conservation under climate change.
