In 3 days ~10%
Leucania stenographa, commonly known as the sugar cane armyworm, is a moth of the family Noctuidae. It is found in Australia, New Zealand and the Cook Islands. This species was first described by Oswald Bertram Lower in 1900 using three specimens collected at Parkside, South Australia in June. In 1905 Hampson synonymised this species with L. uda and this placement was accepted by subsequent authors. In 1953 C. Rungs, after studying the male genitalia characteristics of specimens of the species L. foreyi, named a new species Leucania loreyimima. L. loreyimima was subsequently placed in the genus Mythimna. After a specimen labelled with the name stenographa and collected in Parkside was found in Lower's collection at the South Australian Museum, E. D. Edwards revised the taxonomy of L. loreyimima. He examined the specimen and found that it was identical to the Rungs' illustrations of the holotype used by Rungs when first describing L. loreyimima. As a result Edwards synonymised Leucania loreyimima with L. stenographa and recognised it as a valid species.
The term “Armyworm” is used because of their habit to spread out in a line across a lawn or pasture, and slowly “marching... Wikipedia →

Rare
Under 5% of wildlife watchers report a Sugar Cane Armyworm sighting in Melbourne on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 808th most-seen of the 875 insects we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Sugar Cane Armyworm in Melbourne on a given day, so our monthly data shows no clear season.
2nd of 2
Of the 2 cities where we can rate Sugar Cane Armyworm sightings, Melbourne ranks 2nd at under 5%. The best odds are in Auckland (New Zealand, about 10%).
GBIF citizen-science records
It is estimated from how often the Sugar Cane Armyworm is recorded against all the insects logged in Melbourne (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.
