Females lay eggs in bark crevices on ash trees, and larvae feed underneath the bark of ash trees to emerge as adults in one to two years.

Asian long-horned beetle larvae do not pupate before they reach a critical weight, so additional larval instars can occur. [ 2 ] Pupation usually occurs in spring at the end of the larval tunnel in the sapwood , eclosion occurs 12–50 days later, and adults will chew out of the tree approximately one week after eclosion. [ 2 ]
These beetles cut into the tree by using their clypeus as a chisel. They hold on tightly to the tree and move their head back and forth to cut into the bark. [12] For a short time, sap flows out of the newly made wound, and the Japanese rhinoceros beetle can feed. After a few minutes, the sap stops flowing, so the beetle begins to carve again. [12]
