Bamboo weevil adults emerge from generation to generation, and the adults overwinter in the soil. From June to July of the following year, after the new shoots grow stronger, the adults emerge and feed on the bamboo shoots, mate and lay eggs. The eggs are mostly laid in the shoots, before the oviposition, the adults bite the holes in the shoots, lay the eggs into them, each hole lays 1-2 eggs, the orifice is wet or there are fibrous protrusions, and the eggs hatch after 3-7 days.

The larval stage is 15-19 days. The mature larvae bite the hole in the infested part and fall to the ground, and then burrow into the soil at a depth of 8-10 cm to build a soil chamber to pupate, and the adults emerge and overwinter in the soil. It takes 1 month from egg to adult.

It can be harmful from May to October every year, especially from July to August. After the adult is unearthed, it mostly flies at 8-10 o'clock, and the adult has the ability to fake death.

Adults are good at flying and mostly appear when it is hot, and sometimes at dusk after rain.
