Erionota thrax, the palm redeye or the banana skipper, is a species of butterfly belonging to the family Hesperiidae. It is found from India, through south-eastern Asia to Papua New Guinea. In the north it is found up to southern China. It is an introduced species on various Pacific islands, including the Solomon Islands and Hawaii. It has also been recorded from Mauritius.
The wingspan is 70–77 mm. There are multiple generations per year. The larvae feed on the leaves of Musa species, especially Musa textilis. It has also been recorded on Cocos nucifera and other palm species. The rolls in banana leaves that E. thrax larvae create when feeding have been used as overwintering shelters for wasp species Polistes japonicus in Okinawa, Japan.

Rare
Under 5% of wildlife watchers report a Banana Skipper sighting in Singapore on a given day, based on 8 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 Banana Skipper in Singapore on a given day, so our monthly data shows no clear season.
3rd of 3
Of the 3 cities where we can rate Banana Skipper sightings, Singapore ranks 3rd at under 5%. The best odds are in Yogyakarta (Indonesia, about 20%) and Tasikmalaya (Indonesia, about 20%).
GBIF citizen-science records
It is estimated from how often the Banana Skipper is recorded against all the insects logged in Singapore (8 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.
