Earias perhuegeli, the rough bollworm, is a moth of the family Nolidae. The species was first described by Jeremy Daniel Holloway in 1977. It is found in the northern two-thirds of Australia and several islands in the South Pacific.
The wingspan is about 20 mm. The larvae feed on Gossypium australe, Gossypium populifolium, Abutilon otocarpum, Abelmoschus ficulneus, Hibiscus trionum, Hibiscus panduriformis, Alyogyne hakeifolia and Adansonia gregorii, and are considered a pest of Gossypium hirsutum. Wikipedia →

Rare
Under 5% of wildlife watchers report a Rough Bollworm sighting in Brisbane on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 856th most-seen of the 1083 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
September
In that month about 10% of wildlife watchers report a Rough Bollworm in Brisbane on a given day, against under 5% in October to August, the lowest months. That is one of Brisbane's driest months, with about 40 mm of rain against 160 mm in February.
Among the best
Of the 3 cities where we can rate Rough Bollworm sightings, Brisbane ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Perth (Australia, under 5%).
GBIF citizen-science records
It is estimated from how often the Rough Bollworm is recorded against all the insects logged in Brisbane (7 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.
