With luck
About 10% of wildlife watchers report a Chequered Weevil sighting in Brussels on a given day, based on 13 verified sightings from GBIF citizen-science data. It is the 144th 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
In that month about 20% of wildlife watchers report a Chequered Weevil in Brussels on a given day, against under 5% in May to February, the lowest months. That is one of Brussels's driest months, with about 40 mm of rain against 80 mm in August.
Between 4 and 7 pm
Across all the parks we cover, that three-hour window holds the most Chequered Weevil sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 20 cities where we can rate Chequered Weevil sightings, Brussels ranks 3rd at about 10%, level with the leaders once rounded. The best odds are in Paris (France, about 10%) and Nizhny Novgorod (Russia, about 10%).
Same family: Curculionidae
The closest relatives of the Chequered Weevil that you can see in Brussels (family Curculionidae, True Weevils) are Green Immigrant Leaf Weevil (about 10%), Nettle Weevil (about 10%) and Common Leaf Weevil (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Chequered Weevil is recorded against all the insects logged in Brussels (13 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.
