With luck
About 10% of wildlife watchers report a Polyrhachis arachne sighting in Jakarta on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 151st most-seen of the 239 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
February, April, June, August–September and December
In those months about 10% of wildlife watchers report a Polyrhachis arachne in Jakarta on a given day, against under 5% in January, March, May, July and October–November, the lowest months.
Only Jakarta, in our data

Same genus: Polyrhachis

GBIF citizen-science records
It is estimated from how often the Polyrhachis arachne is recorded against all the insects logged in Jakarta (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.
