Rare
Under 5% of wildlife watchers report a Halyomorpha picus sighting in Bengaluru on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 360th most-seen of the 477 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.
August and September
In those months about 10% of wildlife watchers report a Halyomorpha picus in Bengaluru on a given day, against under 5% in October to July, the lowest months. Those are among Bengaluru's wettest months, with about 130 mm of rain a month against almost none in January.
Only Bengaluru, in our data
Bengaluru is the only city on Wallace's Line with enough records to rate Halyomorpha picus sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Halyomorpha picus is recorded against all the insects logged in Bengaluru (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.
