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 20% of wildlife watchers report a Lychee Stink Bug sighting in Hong Kong on a given day, based on 332 verified sightings from GBIF citizen-science data. It is the 20th most-seen of the 1125 insects we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
April
In that month about 40% of wildlife watchers report a Lychee Stink Bug in Hong Kong on a given day, against under 5% in January and November, 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.
5th of 10
Of the 10 cities where we can rate Lychee Stink Bug sightings, Hong Kong ranks 5th at about 20%. The best odds are in Taipei (Taiwan, about 30%), Taichung (Taiwan, about 30%) and Tuen Mun (China, about 30%).
Same order: Hemiptera
The closest relatives of the Lychee Stink Bug that you can see in Hong Kong (order Hemiptera, True Bugs, Hoppers, Aphids, and allies) are Litchi Lantern Bug (about 20%), Ricania guttata (about 10%) and Speckled Black Cicada (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Lychee Stink Bug is recorded against all the insects logged in Hong Kong (332 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.
