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. They have one pair of ommatidium and one pair of compound eyes, both of which are red. The antennae have four segments and are dark brown. The prothorax is tilted forward and downward. 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 →

Possible
About 30% of wildlife watchers report a Lychee Stink Bug sighting in Taipei on a given day, based on 698 verified sightings from GBIF citizen-science data. It is the 2nd most-seen of the 765 insects we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
April and May
In those months about 40% of wildlife watchers report a Lychee Stink Bug in Taipei on a given day, against about 10% in September to February, the lowest months.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Lychee Stink Bug sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 10 cities where we can rate Lychee Stink Bug sightings, Taipei has the highest daily chance: about 30%. Next come Taichung (Taiwan, about 30%) and Tuen Mun (China, about 30%).
GBIF citizen-science records
It is estimated from how often the Lychee Stink Bug is recorded against all the insects logged in Taipei (698 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
