This pest has one generation per year. The larva overwintered in the soil, and pupated at the last ten days of March to the first ten days of April in the soil layer of 3-10cm under the ground. The pupal period ranged from 12 to 17 days.

此虫一年一代，以幼虫在土中越冬；翌年3月下旬至4月上旬在3—10厘米土层内化蛹，蛹期12—17天；4月中、下旬成虫出土上树取食桑芽和叶片，交尾后2—7天产卵在枝顶及春季剪梢口下段等处，每头雌成虫产卵44—205粒，卵期15—19天；初孵幼虫入土取食植物。
