With luck
About 10% of wildlife watchers report a Yellow-Vented Hornet sighting in Yogyakarta on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 90th most-seen of the 141 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
May–June and September
In those months about 30% of wildlife watchers report a Yellow-Vented Hornet in Yogyakarta on a given day, against under 5% in April, August and October–February, the lowest months. Those are among Yogyakarta's driest months, with about 100 mm of rain a month against 350 mm in January.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Yellow-Vented Hornet sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
2nd of 11
Of the 11 cities where we can rate Yellow-Vented Hornet sightings, Yogyakarta ranks 2nd at about 10%. The best odds are in Nagoya (Japan, about 20%).
Same genus: Vespa
The closest relatives of the Yellow-Vented Hornet that you can see in Yogyakarta (genus Vespa, Hornets) are Lesser Banded Hornet (about 30%) and Greater Banded Hornet (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Yellow-Vented Hornet is recorded against all the insects logged in Yogyakarta (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.
