In 3 days ~50% in a week ~80%
Lyramorpha rosea, commonly known as the lychee stink bug, is a species of stink bug in the family Tessaratomidae. It is found in eastern Australia. According to the original species description by Westwood, L. rosea has legs and antennae pink (rosea in the original Latin), the margins of the thorax and hemelytra are bronze, and the underside of the body is greenish-yellow.
The body length, also according to the original description, is 11 lines. In entomology, a line is equal to one-twelfth of an inch, so this is equivalent to a length of ~0.917 inches or ~2.328 centimetres. Lyramorpha rosea feeds on plants in the family Sapindaceae. Its native host plants are in the genera Alectryon, Atalaya, Cupaniopsis and Guioa. It also feeds on the exotic lychee (Litchi chinensis). There are records of it on plants in other families, but these require confirmation.
Females brood their eggs, in clutches of up to 42, until they hatch. Wikipedia →

Possible
About 20% of wildlife watchers report a Lychee Stink Bug sighting in Royal National Park on a given day, based on 50 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 16th most-seen of the 175 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.
February
In that month about 40% of wildlife watchers report a Lychee Stink Bug in Royal National Park on a given day, against under 5% in May and August, the lowest months.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Lychee Stink Bug sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
2nd of 5
Of the 5 parks where we can rate Lychee Stink Bug sightings, Royal National Park ranks 2nd at about 20%. The best odds are in Noosa National Park (Australia, about 30%).
GBIF citizen-science records
It is estimated from how often the Lychee Stink Bug is recorded against all the insects logged in Royal National Park (50 verified sightings from 2019 to 2026), 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.
