Every year, adults come out of the soil in the first half of May. Adults will pierce the peel of citrus fruits from the second half of May to the first half of July, then lay eggs and hatch into larvae inside the fruits. Larvae will grow with citrus pulp as nutrition. By September, the damaged fruits turned yellow ahead of time, and most of them naturally fell off. After the damaged fruit fell to the ground, the larvae overwintered in the soil and pupated, and were unearthed in May of the following year.
