Musgraveia sulciventris is a Tessaratomid bug found in Australia, sometimes known as the bronze orange bug. It is considered a pest, particularly to plants in the citrus group. Bronze orange bugs suck the sap from trees, which causes the flowers and fruit to fall.
In 1863, Swedish entomologist Carl Stål described the species as Oncoscelis sulciventris from a collection near Moreton Bay in Queensland. In 1957, English entomologists Dennis Leston and G.G.E. Scudder reclassified the bronze orange bug as Musgraveia sulciventris, due to reorganization of Oncoscelis and related genera. It is the type species of the genus Musgraveia and in the Tessaratomidae family.
Bronze orange bugs are first found on trees in late winter. Mating takes place between late November through early March. Each mating pair takes 3 to 5 days to produce 10 to 14 eggs. The female lays up to four clutches of eggs and deposits them on the undersurface of a leaf. The bright green spherical eggs are around 2.5 mm (0.1 in) in diameter. The incubation period varies based on current weather conditions. Hatching averages around 7.4 days at 25 °C and 6 percent humidity. As a... Wikipedia →

With luck
About 10% of wildlife watchers report a Bronze Orange Bug sighting in Springbrook National Park on a given day, based on 12 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 138th most-seen of the 429 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 50%, if each day is a fresh chance.
December
In that month about 20% of wildlife watchers report a Bronze Orange Bug in Springbrook National Park on a given day, against under 5% in February and April–August, the lowest months.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Bronze Orange Bug sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 3 parks where we can rate Bronze Orange Bug sightings, Springbrook National Park ranks 3rd at about 10%, level with the leaders once rounded. The best odds are in Royal National Park (Australia, about 10%) and Blue Mountains National Park (Australia, about 10%).
GBIF citizen-science records
It is estimated from how often the Bronze Orange Bug is recorded against all the insects logged in Springbrook National Park (12 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.
