First singing data of Graptopsaltria nigrofuscata and weather data

Data set used in a study that used long-term phenology data to explore key weather factors that affect the emergence of the Graptopsaltria nigrofuscata and detect the effects of climate change. This study showed that the emergence of Graptopsaltria nigrofuscata was influenced by higher temperatures during the summer to winter of the previous year. The effects of other climate factors such as precipitation and humidity were small. The annual increase in temperature caused by climate change was causing the advancement of cicada emergence patterns. The data consisted of long-term observations by the Japan Meteorological Agency, the last three years of data from citizen scientists, and weather data at the respective observation sites., , , # First singing data of *Graptopsaltria nigrofuscata* and weather data
