Tessaratoma papillosa, the lychee giant stink bug, is a species of bug in the family Tessaratomidae. It is found in Indomalaya, Australasia, and Eastern Asia. It feeds on the buds, shoots, flower sprigs, and fruits of lychee and longan trees using its piercing and sucking mouthparts. This feeding can cause major damage to the tree, causing its fruits and flowers to drop off and the withering of twigs and fruits. A tree that is fed upon by many T. papillosa may experienced retarded growth or even death. For this reason, T. papillosa is considered an agricultural pest, causing considerable economic losses for farmers in affected regions.
Adult Tessaratoma papillosa have a shield-shaped body with yellowish-brown coloration. They have a body length of 24-28mm and a width of 15-17mm. Females are slightly larger than males.

It has odor glands near the front of the metathoracic side plate and white wax powder covering the ventral surface of the thorax. The female has a longitudinal slit in... Wikipedia →
