In 3 days ~40% in a week ~70%
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 →

With luck
About 10% of wildlife watchers report a Lychee Stink Bug sighting in Brisbane on a given day, based on 287 verified sightings from GBIF citizen-science data. It is the 42nd most-seen of the 1083 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
December
In that month about 30% of wildlife watchers report a Lychee Stink Bug in Brisbane on a given day, against under 5% in June and July, the lowest months. That is one of Brisbane's wettest months, with about 130 mm of rain against 40 mm in July.
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 2
Of the 2 cities where we can rate Lychee Stink Bug sightings, Brisbane ranks 2nd at about 10%. The best odds are in Sydney (Australia, about 20%).
GBIF citizen-science records
It is estimated from how often the Lychee Stink Bug is recorded against all the insects logged in Brisbane (287 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.
