Neoplocaederus obesus, commonly known as cashew stem borer or red cocoon-making longhorn,[1] is a species of longhorn beetle native to South Asian and South East Asian countries.

[2][3] It is found in Sri Lanka, India, Andaman, Nicobar,[4] Bangladesh, Myanmar, Thailand,[5] Vietnam, Laos, China, Taiwan, and Bhutan.

[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.

Adults are visible from January to May usually emerged with pre monsoon rains.
