Correlation analyses between daily moth catch and ambient temperatures on each catch day. At the Mt. Usu rest area in 2014 (a), the gypsy moth catch was correlated more strongly with the highest temperature than with the dusk temperature, but the opposite correlations were found in Yubari in 2018 (b). There were no correlations between oak moth catch and the highest temperature and dusk temperature (c). The highest number of gypsy moths was trapped when ambient temperatures ranged from 22 to 24 °C, but the number decreased at temperatures above 24 °C (d)
