With luck
About 10% of wildlife watchers report a Lesser Banded Hornet sighting in Kuala Lumpur on a given day, based on 10 verified sightings from GBIF citizen-science data. It is the 161st most-seen of the 323 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.
March, June–August and October–November
In those months about 10% of wildlife watchers report a Lesser Banded Hornet in Kuala Lumpur on a given day, against under 5% in April–May, September and December–February, the lowest months.
Between 6 and 9 am
Across all the parks we cover, that three-hour window holds the most Lesser Banded Hornet sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
22nd of 24
Of the 24 cities where we can rate Lesser Banded Hornet sightings, Kuala Lumpur ranks 22nd at about 10%. The best odds are in Yogyakarta (Indonesia, about 30%), Jamshedpur (India, about 30%) and Phnom Penh (Cambodia, about 20%).
GBIF citizen-science records
It is estimated from how often the Lesser Banded Hornet is recorded against all the insects logged in Kuala Lumpur (10 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.
