Rare
Under 5% of wildlife watchers report a Diademed Woolcarder sighting in Madrid on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 409th most-seen of the 457 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
July
In that month about 10% of wildlife watchers report a Diademed Woolcarder in Madrid on a given day, against under 5% in August to June, the lowest months. That is one of Madrid's driest months, with about 10 mm of rain against 65 mm in October.
Only Madrid, in our data
Madrid is the only city on Wallace's Line with enough records to rate Diademed Woolcarder sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Diademed Woolcarder is recorded against all the insects logged in Madrid (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.
