Rare
Under 5% of wildlife watchers report a Horned Woodborer sighting in Warsaw on a given day, based on 11 verified sightings from GBIF citizen-science data. It is the 413th most-seen of the 580 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.
July and September
In those months about 10% of wildlife watchers report a Horned Woodborer in Warsaw on a given day, against under 5% in August and October–June, the lowest months.
Only Warsaw, in our data
Warsaw is the only city on Wallace's Line with enough records to rate Horned Woodborer sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Megachilidae
The closest relatives of the Horned Woodborer that you can see in Warsaw (family Megachilidae, Mason, Leafcutter, Carder, and Resin Bees) are Red Mason Bee (about 20%), European Woolcarder Bee (about 20%) and European Orchard Bee (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Horned Woodborer is recorded against all the insects logged in Warsaw (11 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.
