Rare
Under 5% of wildlife watchers report a Vestigial Weeper sighting in Brussels on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 260th most-seen of the 337 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
April and May
In those months about 10% of wildlife watchers report a Vestigial Weeper in Brussels on a given day, against under 5% in June to March, the lowest months.
Only Brussels, in our data
Brussels is the only city on Wallace's Line with enough records to rate Vestigial Weeper sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Tenthredinidae
The closest relatives of the Vestigial Weeper that you can see in Brussels (family Tenthredinidae, Common Sawflies) are Turnip Sawfly (about 10%) and Saddleback Grass-Cutter (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Vestigial Weeper is recorded against all the insects logged in Brussels (6 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.
