为了研究季节昆虫对环境变化的反应，从7月下旬到8月，在日本中部郊区的一处栖息地对两种蝉的若虫皮肤进行了每周监测。基于1995年至2006年收集的8000多张皮肤，作者估计了温度或降水影响皮肤丰富度和物候的时期。面纹夜蛾的成虫往往比黑褐斑潜蝇更早羽化，黑褐斑潜蝇的总皮肤数在不同年份间波动高达7倍。从之前的3.0-3.5个月到最近的1.0-1.5个月的有效积温，阈值约为>；18摄氏度，与一个季节内的累积皮肤计数最吻合。温度对面纹夜蛾皮片数总变异的贡献率为47%，对黑褐斑潜蝇皮片数总变异的贡献率为。温度对雄性蝉和雌性蝉产生这种影响的时间点是一致的。相反，累积降雨量占了
To investigate how seasonal insects respond to changing environments, nymphal skins of the two cicadas Cryptotympana facialis (Walker) and Graptopsaltria nigrofuscata (Motschulsky) (Hemiptera: Cicadidae) were monitored weekly from late July to August over 12 yr in a suburban habitat of central Japan. Based on over 8,000 skins collected from 1995 to 2006, the authors estimated the period during which temperature or precipitation impacted skin abundance and phenology. Adults of C. facialis tended to emerge earlier than those of G. nigrofuscata, for which total skin counts fluctuated up to sevenfold among years. The effective accumulated temperature from the previous 3.0-3.5mo to the most recent 1.0-1.5mo at a threshold of approximately >18 degrees C showed the best fit to the cumulative skin counts within a season. Temperature explained 47 and 64% of the total variation in the skin counts for C. facialis and G. nigrofuscata, respectively. The point at which temperature had this effect was consistent between male and female cicadas. Conversely, accumulated precipitation accounted for
