Distribution

It is found in Sri Lanka, India, Andaman, Nicobar, ^[4] Bangladesh, Myanmar, Thailand, ^[5] Vietnam, Laos, China, Taiwan, and Bhutan. ^[6]

Biology

Male is usually smaller in size with 38 mm and female is approximately 40 mm. ^[7]

Particularly as sap wood borer, the female lays about 40–50 eggs in the live tissues or in the crevices of the bark at the collar region. Grubs then bore into the fresh tissues of the bark and gradually move through the sap wood by making tunnels. Finally they reach roots. Grubs feed the internal tissues for about 3–6 months. ^[8] Pupal stage is about 3 to 4 months. Adults are visible from January to May usually emerged with pre monsoon rains. ^{[9] [10]}
