With luck
About 10% of wildlife watchers report a Maple Gall Wasp sighting in Brussels on a given day, based on 22 verified sightings from GBIF citizen-science data. It is the 92nd most-seen of the 337 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.
April–August and October
In those months about 10% of wildlife watchers report a Maple Gall Wasp in Brussels on a given day, against under 5% in September and November–March, the lowest months.
Between 3 and 6 pm
Across all the parks we cover, that three-hour window holds the most Maple Gall Wasp sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 5 cities where we can rate Maple Gall Wasp sightings, Brussels ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Paris (France, about 10%).
Same order: Hymenoptera
The closest relatives of the Maple Gall Wasp that you can see in Brussels (order Hymenoptera, Ants, Bees, Wasps, and Sawflies) are Yellow-Legged Hornet (about 40%), Common Carder Bumble Bee (about 20%) and European Hornet (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Maple Gall Wasp is recorded against all the insects logged in Brussels (22 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.
