In 3 days ~30% in a week ~60%
Epiblema strenuana, the stem-galling moth or ragweed borer, is a moth of the family Tortricidae. It is endemic to North America, but was introduced to Australia from Mexico to control the weeds of the family Asteraceae (Xanthium occidentale, Ambrosia artemisiifolia and Parthenium hysterophorus) in 1982. It is occasionally misspelled as Epiblema strenuanum.
The wingspan is about 15 mm. The larvae mainly feed on Asteraceae species, including Ambrosia and Xanthium. It has also been recorded on Chenopodium species. Wikipedia →

With luck
About 10% of wildlife watchers report a Ragweed Borer Moth sighting in Lamington National Park on a given day, based on 13 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 131st most-seen of the 430 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
February and March
In those months about 30% of wildlife watchers report a Ragweed Borer Moth in Lamington National Park on a given day, against under 5% in April to January, the lowest months. Those are among Lamington National Park's wettest months, with about 160 mm of rain a month against 40 mm in August.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Ragweed Borer Moth sightings with a recorded time, and about 9 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Only Lamington National Park, in our data
Lamington National Park is the only park on Wallace's Line with enough records to rate Ragweed Borer Moth sightings: about 10% of wildlife watchers there report one on a given day.
Same family: Tortricidae
The closest relatives of the Ragweed Borer Moth that you can see in Lamington National Park (family Tortricidae, Tortricid Leafroller Moths) are Loboschiza koenigiana (about 10%), Goboea copiosana (about 10%) and Orange Fruit Borer (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Ragweed Borer Moth is recorded against all the insects logged in Lamington National Park (13 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.
