Lethe confusa, the banded treebrown, is a species of butterfly belonging to the satyr family that is found mainly in Southeast Asia and in parts of South Asia. It is about 50–55 mm in expanse, with the upper surface of wings predominantly brown in colour. The forewing has a sub-apical white band and pale spot on the apex. The underside of the hindwing has a large ocellus or and a series of spots along the margin. It is found in bamboo forests.
Hindwing dentate at apex of vein 4. Upperside ground colour Vandyke brown; forewing crossed by an oblique, slightly curved, discal white band, the margins of the band more even and regular than in the female of Lethe rohria; beyond this are two obliquely placed preapical white spots. Hindwing uniform, ocelli of the underside showing through.
Underside uniform brown; forewings and hindwings with subbasal, subterminal and terminal sinuous lilacine-white lines; forewing with the oblique discal white bar as on the upperside, followed by a subapical lilacine patch bearing three small ocelli in vertical order, and with a very short, oblique, white bar joining it to the costa.

With luck
About 10% of wildlife watchers report a Banded Treebrown sighting in Hong Kong on a given day, based on 135 verified sightings from GBIF citizen-science data. It is the 84th most-seen of the 1125 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.
July and August
In those months about 20% of wildlife watchers report a Banded Treebrown in Hong Kong on a given day, against under 5% in January–February and October, the lowest months. Those are among Hong Kong's wettest months, with about 200 mm of rain a month against 25 mm in December.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Banded Treebrown sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
2nd of 4
Of the 4 cities where we can rate Banded Treebrown sightings, Hong Kong ranks 2nd at about 10%. The best odds are in Kathmandu (Nepal, about 20%).
GBIF citizen-science records
It is estimated from how often the Banded Treebrown is recorded against all the insects logged in Hong Kong (135 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.
