With luck
About 10% of wildlife watchers report a Seven-Spined Woolcarder sighting in Vienna on a given day, based on 130 verified sightings from GBIF citizen-science data. It is the 145th most-seen of the 1406 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.
July
In that month about 20% of wildlife watchers report a Seven-Spined Woolcarder in Vienna on a given day, against under 5% in October to May, the lowest months. That is one of Vienna's wettest months, with about 90 mm of rain against 40 mm in February.
Among the best
Of the 6 cities where we can rate Seven-Spined Woolcarder sightings, Vienna ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Paris (France, about 10%).
GBIF citizen-science records
It is estimated from how often the Seven-Spined Woolcarder is recorded against all the insects logged in Vienna (130 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.
