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 Melbourne on a given day, based on 11 verified sightings from GBIF citizen-science data. It is the 619th most-seen of the 875 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.
March
In that month about 10% of wildlife watchers report a Rough Bollworm in Melbourne on a given day, against under 5% in April to February, the lowest months.
Among the best
Of the 3 cities where we can rate Rough Bollworm sightings, Melbourne ranks 3rd at under 5%, level with the leaders once rounded. The best odds are in Perth (Australia, under 5%) and Brisbane (Australia, under 5%).
GBIF citizen-science records
It is estimated from how often the Rough Bollworm is recorded against all the insects logged in Melbourne (11 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.
