The family Stathmopodidae, which belongs to to the superfamily Gelechioidea, has 6 genera and 18 species reported in Korea to date. This family is classified as pests, causing serious damage to grains or fruits, depending on the species. Therefore, precise control is necessary, however, there is a lack of taxonomic and ecological research. We aim to analyze the clade and speciation timing for phylogenetic analysis of Stathmopodidae using ChatGPT, a tool that has recently garnered much attention. ChatGPT, a conversational AI chatbot developed by OpenAI, is accessible to anyone and being able to improve itself through conversations with users. In this study, we utilized the lengths of the generated lineage branches and the molecular clock rate to predict when certain species of the family Stathmopodidae diverged, measured in millions of years. However, further study is required to obtain more accurate figures.
