The pupae remain dormant in the soil until they emerge as adult moths in the winter.蛹一直都在土壤中蛰伏直到冬季长成成蛾。Bears hole up for the winter to go by.熊蛰伏穴中等待冬天过去。Hibernating insects begin to move.蛰伏的昆虫们开始活动。This is when the pilots who have been hibernating during the winter months start flying again.这就是在冬月里一直蛰伏的飞行员们重新飞上天空的时候。
