The species is considered very rare. A small butterfly, 40 to 50 mm in wingspan, it is the largest of the genus. The upper forewing in both sexes has a broad white discal band which extends right up to dorsum, the upper edge of which is sharply angled at vein 3. The upper hindwing has a pale discal streak.
The male has the upperside of wings dusky brownish black. The ground colour of the forewings darker, almost pure black in fresh specimens, on the apical third of the wing; a short streak in the middle of interspace 1, a more outwardly produced similar streak in interspace 2, basal halves of interspaces 3 and 4, the lower apex of the discoidal cell and the extreme base of interspace 5, white, all forming a median conspicuous irregular white patch on the wing, narrowly traversed by the veins which are greyish brown.

Rare
Under 5% of wildlife watchers report a Great Brownie sighting in Singapore on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 788th most-seen of the 1045 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Great Brownie in Singapore on a given day, so our monthly data shows no clear season.
Only Singapore, in our data
Singapore is the only city on Wallace's Line with enough records to rate Great Brownie sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Great Brownie is recorded against all the insects logged in Singapore (9 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.
