Life history and habits: Pygmy bees occur one generation in one year, and the mature larvae in the soil cover the winter, with the largest amount of soil within a metre radius from the trunk. Overwintering larvae begin to grow into pods and pears in the bud of pear trees. Embryos emerged from buds. The early stage of Pear Blossom is the peak period of adult emergence. The feathering ends before flowering. When the pear blossoms, most of the adults feed on the pear tree for spawning. After the spawning, fecal secretions are used to block the spawning hole and become a black dot. The larvae are harmed within the fruit for about 20 days. The larvae are released after the old ones are ripe and fall into the ground. Then the spit makes an elliptical wart and it will pass through winter.
