Lyramorpha rosea
In 3 days ~70% in a week ~90%
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 30% of wildlife watchers report a Lychee Stink Bug sighting in Noosa National Park on a given day, based on 40 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the most-seen of the 32 insects we can rate there. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.
January and October

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.
Yes
Of the 5 parks where we can rate Lychee Stink Bug sightings, Noosa National Park has the highest daily chance: about 30%. Next come Royal National Park (Australia, about 20%) and Lamington National Park (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 Noosa National Park (40 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.
